Crystal structure and the DFT and MEP study of 4-benzyl-2-[2-(4-fluoro-phen-yl)-2-oxoeth-yl]-6-phenyl-pyridazin-3(2H)-one.

The title pyridazin-3(2H)-one derivative, C25H19FN2O2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule A, the 4-fluoro-phenyl ring, the benzyl ring and the phenyl ring are inclined to the central pyridazine ring by 86.54 (11), 3.70 (9) and 84.857 (13)°, respectively. In mol-ecule B, the corresponding dihedral angles are 86.80 (9), 10.47 (8) and 82.01 (10)°, respectively. In the crystal, the A mol-ecules are linked by pairs of C-H⋯F hydrogen bonds, forming inversion dimers with an R 2 2(28) ring motif. The dimers are linked by C-H⋯O hydrogen bonds and a C-H⋯π inter-action, forming columns stacking along the a-axis direction. The B mol-ecules are linked to each other in a similar manner and form columns separating the columns of A mol-ecules.

Chemical context

Pyridazin-3(2H)-ones are pyridazine derivatives, being constructed about a six-membered ring that contains two adjacent nitro­gen atoms, at positions one and two, and with a carbonyl group at position three. The inter­est in these nitro­gen-rich heterocyclic derivatives arises from the fact that they exhibit a number of promising pharmacological and biological activities. These include anti-oxidant (Khokra et al., 2016 ▸), anti-bacterial and anti-fungal (Abiha et al. 2018 ▸), anti-cancer (Kamble et al. 2017 ▸), analgesic and anti-inflammatory (Ibrahim et al. 2017 ▸), anti-depressant (Boukharsa et al. 2016 ▸) and anti-ulcer activities (Yamada et al., 1981 ▸). In addition, a number of pyridazinone derivatives have been reported to have potential as agrochemicals, for example as insecticides (Nauen & Bretschneider, 2002 ▸), acaricides (Igarashi & Sakamoto, 1994 ▸) and herbicides (Aza­ari et al., 2016 ▸). The present work is a part of an ongoing structural study of heterocyclic compounds and their utilization as mol­ecular (Faizi et al., 2016 ▸) and fluorescence (Mukherjee et al., 2018 ▸; Kumar et al., 2017 ▸; 2018 ▸) sensors. Given the inter­est in this class of compounds and the paucity of structural data, the crystal structure analysis of the title pyridazin-3(2H)-one derivative has been undertaken, along with a DFT study, in order to gain further insight into the mol­ecular structure.

Structural commentary

The title compound crystallizes with two independent mol­ecules (A and B) in the asymmetric unit (Fig. 1 ▸). In each mol­ecule, a central oxopyridazinyl ring is connected to a fluoro­benzyl­acetate group, a phenyl group, and a benzyl residue. The oxopyridazinyl ring (B) is planar in both mol­ecules; r.m.s. deviations are 0.029 Å for mol­ecule A and 0.009 Å for mol­ecule B. In mol­ecule A, the 4-fluoro­phenyl ring (A; C1A–C6A), the benzyl ring (C; C20A–C25A) and the phenyl ring (D; C13A–C18A) are inclined to the central pyridazine ring (B; N1A/N2A/C9A–C12A) by 86.54 (11), 3.70 (9) and 84.87 (13)°, respectively. In mol­ecule B, the corresponding dihedral angles are 86.80 (9), 10.47 (8) and 82.01 (10)°, respectively. Hence, the conformation of the two mol­ecules differs essentially in the orientation of the benzyl ring (C) with respect to the central pyridazine ring (B); 3.70 (9)° in mol­ecule A compared to 10.47 (8)° in mol­ecule B. The two mol­ecules have an r.m.s. deviation of 0.683 Å for the 30 non-hydrogen atoms (Fig. 2 ▸; PLATON; Spek, 2009 ▸).

Supra­molecular features

In the crystal, the A mol­ecules are linked by pairs of C—H⋯F hydrogen bonds, forming inversion dimers with an (28) ring motif (Table 1 ▸ and Fig. 3 ▸). The dimers are linked by C—H⋯O hydrogen bonds and a C—H⋯π inter­action (Table 1 ▸), forming columns stacking along the a-axis direction. The B mol­ecules are linked to each other in a similar manner (Table 1 ▸), and also form columns separating the columns of A mol­ecules, as illustrated in Fig. 3 ▸.

Frontier mol­ecular orbitals analysis

The highest occupied mol­ecular orbitals (HOMOs) and the lowest-lying unoccupied mol­ecular orbitals (LUMOs) are named as frontier mol­ecular orbitals (FMOs). The FMOs play an important role in the optical and electric properties, as well as in quantum chemistry and UV–vis spectra. As a result of the inter­action between the HOMO and LUMO orbitals of a structure, a transition state of the π–π* type is observed according to mol­ecular orbital theory. The frontier orbital gap helps characterize the chemical reactivity and the kinetic stability of the mol­ecule. A mol­ecule with a small frontier orbital gap is generally associated with a high chemical reactivity, low kinetic stability and is also termed as a soft mol­ecule. The DFT quantum-chemical calculations for the title compound were performed at the B3LYP/6–311 G(d,p) level (Becke, 1993 ▸) as implemented in GAUSSIAN09 (Frisch et al., 2009 ▸). The DFT structure optimization was performed starting from the X-ray geometry and the experimental values of the bond lengths and bond angles match the theoretical values. The DFT study shows that the HOMO and LUMO are localized in the plane extending from the whole substituted oxopyridazinyl ring. The electron distribution of the HOMO−1, HOMO, LUMO and LUMO+1 energy levels is shown in Fig. 4 ▸. The HOMO mol­ecular orbital exhibits both σ and π character, whereas HOMO−1 is domin­ated by π-orbital density. The LUMO is mainly composed of π-density while LUMO+1 has both σ and π electronic density. The HOMO–LUMO gap is 0.15669 a.u. and the frontier mol­ecular orbital energies, E HOMO and E LUMO are −0.22571 and −0.06902 a.u., respectively.

Mol­ecular electrostatic potential surface analysis

The mol­ecular electrostatic potential (MEP) is a technique of mapping electrostatic potential onto the iso-electron density surface. The MEP surface provides information about the reactive sites. The colour scheme is as follows: red for electron rich, partial negative charge; blue for electron-deficient, partial positive charge; light blue for a slightly electron deficient region; yellow for a slightly electron-rich region; green for neutral (Politzer & Murray, 2002 ▸). In addition to these, in the majority of the MEPs, while the maximum positive region, which is the preferred site for nucleophilic attack, is indicated in blue, the maximum negative region, which is the preferred site for electrophilic attack, is indicated in red. The three-dimensional plot of the MEP of the title compound is shown in Fig. 5 ▸. According to the MEP map results, the negative regions of the whole mol­ecule are located on donor oxygen atoms (red regions). The resulting surface simultaneously displays the mol­ecular size and shape and electrostatic potential values. As can be seen from the MEP map contours, regions having negative potential are over the electronegative atoms (viz. atoms O1A and O2A of mol­ecule A and O1B and O2B of mol­ecule B). The positive regions are over hydrogen atoms, indicating that these sites are the most likely to be involved in nucleophilic processes.

Database survey

A search of the Cambridge Structural Database (CSD, version 5.40, update February 2019; Groom et al., 2016 ▸) gave zero hits for the skeleton of the title compound. A search for pyridazin-3(2H)-ones gave 297 hits, while a search for 6-phenyl-pyridazin-3(2H)-ones gave 40 hits, including 6-phenyl-pyridazin-3(2H)-one itself (CSD refcode CUBBOR; Anderson et al., 2009 ▸). A search for 4-benzyl-6-phenyl-pyridazin-3(2H)-ones gave only three hits, for example 4-(4-bromo­benz­yl)-6-phenyl­pyridazin-3(2H)-one (VOPMOE; Tsai et al., 2014 ▸). A search for pyridazin-3(2H)-ones with an oxoethyl group in position-2 on the pyridazine ring gave eight hits, mostly esters. Four of these structures also have a phenyl substituent in position-6 on the pyridazine ring, as in the title compound. They include, for example 2-(6-oxo-3,4-diphenyl-1,6-di­hydro­pyridazin-1-yl)acetic acid (CIPTOL; Aydın et al., 2007 ▸).

Synthesis and crystallization

A mixture of 4-benzyl-6-phenyl­pyridazin-3(2H)-one (1 g, 3.8 mmol), K2CO3 (1.3 g, 9.5 mmol) and 2-chloro-1-(4-fluoro­phen­yl)ethan-1-one (1.58 g, 5 mmol) in acetone (40 ml), was refluxed overnight. The solution was then filtered by suction and the solvent removed under reduced pressure. The residue was purified by recrystallization from ethanol to afford the title compound as colourless prismatic crystals (yield 68%).

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The carbon-bound H atoms were placed in calculated positions (C—H = 0.93–0.97 Å) and included in the refinement in the riding-model approximation, with U iso(H) = 1.2U eq(C). The image plate disc in the diffractometer used for the data collection was unfortunately distorted at the outer edges, hence the maximum 2θ value available was limited to 48.8°.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
