Abstract

The complex of 2,4,6-tri-ethyl-1,3,5-tris-[(4-methyl-1H-indazol-1-yl)meth-yl]-benz-ene with ammonium hexa-fluorophosphate, C39H42N6·NH4 +·PF6 -, crystallizes in the monoclinic space group P21 with two mol-ecules of the receptor, two NH4 + and two PF6 - ions in the asymmetric unit. In each of the complexes the ammonium ion resides in the cavity of the receptor mol-ecule and is fixed in its position by three N-H⋯N bonds, while the remaining hydrogen atom of the cation acts as a bifurcated binding site for N-H⋯F bonding to the counter-anion. The crystal is composed of one-dimensional supra-molecular aggregates extending along the a-axis direction. © Fuhrmann et al. 2022.

Chemical context

The development of efficient artificial receptors that exhibit high selectivity for ammonium versus potassium ions is of great inter­est (Bühlmann et al., 1998 ▸; Chin et al., 1999 ▸; Späth & König, 2010 ▸; Pazik & Skwierawska, 2014 ▸; Jonah et al., 2017 ▸; Schulze et al., 2018 ▸). Both acyclic and macrocyclic receptors have been designed to achieve this goal. Tripodal and hexa­podal benzene derivatives bearing pyrazolyl or indazolyl groups have proven to be promising as receptors for NH4 + (Chin et al., 1999 ▸, 2002 ▸; Koch et al., 2015 ▸; Jonah et al., 2017 ▸; Schulze et al., 2018 ▸). The ability of these compounds to act as ammonium receptors has been examined both in solution and in the crystalline state. Structural variations are to be used to develop receptor mol­ecules that exhibit a more pronounced selectivity. As part of our studies on structure–binding affinity relationships, we have synthesized various acyclic mol­ecules and investigated their binding properties. In this work we describe the crystal structure of a complex between NH4PF6 and a tripodal benzene derivative bearing 4-methyl-indazol-1-yl groups.

Structural commentary

Crystallization from a mixture of the title compound and NH4PF6 in ethanol yields colourless prisms of the monoclinic space group P21 with two mol­ecules of the receptor, two NH4 + ions and two PF6 − ions in the asymmetric unit. These components are connected to form complexes of the structures shown in Fig. 1 ▸. In each of them, the NH4 + ion resides in a cavity created by the indazolyl groups of the receptor and is held in its position by three N—H⋯N bonds [d(H⋯N) 2.01 (2)–2.10 (4) Å], involving the nitro­gen atoms designated N2, N4, N6 and N2A, N4A, N6A. The remaining H atom of the ammonium acts as a bifurcated binding site for N—H⋯F bonding with the counter-ion. The conformational difference between the receptor mol­ecules is seen in the orientation of the three ethyl groups, leading to an ab′ab′ab′ (complex I) and an ab′aa′ab′ arrangement (complex II) (a = above, b = below, a′/b′ = ethyl; see Koch et al., 2017 ▸; Schulze et al., 2017 ▸) of substituents with respect to the plane of the central arene ring (Fig. 2 ▸). The dihedral angles between the planes of the indazole units are 67.8 (1), 8.1 (2), 72.6 (1)° for complex I and 62.0 (1), 6.9 (2), 65.4 (1)° for complex II.

Supra­molecular features

The crystal is composed of one-dimensional supra­molecular aggregates of C—H⋯F-bonded ammonium complexes [d(H⋯F) 2.33–2.52 Å; Table 1 ▸] extending in the a-axis direction. The packing is shown in Fig. 3 ▸. Multiple π–π arene contacts connect these aggregates into a three-dimensional network. For the analysis of this type of inter­actions, the PLATON program (Spek, 2020 ▸) was used. The centroid–centroid distances between the inter­acting indazole units range from 3.776 (4) to 4.257 (4) Å with shifts of 1.154–1.830 Å.

Database survey

A search in the Cambridge Structural Database (CSD, Version 5.40, updated February 2019; Groom et al., 2016 ▸) for ammonium complexes of 1,3,5-substituted 2,4,6-tri­alkyl­benzenes bearing pyrazolyl or indazolyl units gave eight hits, all of which contain complexes with NH4PF6. The complexes of 1,3,5-tris­[(3,5-dimethyl-1H-pyrazol-1-yl)meth­yl]-2,4,6-tri­ethyl­benz­ene (CUKTUX; Chin et al., 1999 ▸), 1,3,5-tris­[(4-bromo-3,5-di­methyl-1H-pyrazol-1-yl)meth­yl]-2,4,6-tri­ethyl­benzene (UFO­HOM; Chin et al., 2002 ▸), 1,3,5-tris­[(1H-pyrazol-1-yl)meth­yl]-2,4,6-tri­methyl­benzene (QIFFAP; Schulze et al., 2018 ▸), 1,3,5-tris­[(3,5-dimethyl-1H-pyrazol-1-yl)meth­yl]-2,4,6-tri­methyl­ben­z­ene (QIDTOP; Schulze et al., 2018 ▸) and 1,3,5-tris­[(4-bromo-3,5-dimethyl-1H-pyrazol-1-yl)meth­yl]-2,4,6-tri­methyl­benzene (QIDTUV; Schulze et al., 2018 ▸) have the most similar structures to that of the title complex. In the crystal structure of the complex formed by 1,3,5-tris­[(4-bromo-3,5-dimethyl-1H-pyrazol-1-yl)meth­yl]-2,4,6-tri­ethyl­benzene (QIDVOR; Schulze et al., 2018 ▸), which also contains aceto­nitrile mol­ecules, the complex lacks NH4 +⋯F6P− inter­actions. Instead, one of the solvent mol­ecules is connected to the cation via N—H⋯N bonding whereas the PF6 − ion is coordinated to the receptor and the solvent mol­ecules. In the crystal of the complex of 1,3,5-tris­[(3,5-diphenyl-1H-pyrazol-1-yl)meth­yl]-2,4,6-tri­ethyl­benzene (XEKBEX; Jonah et al., 2017 ▸) the steric demand of the phenyl groups attached to the pyrazole rings prevents cation–anion inter­actions. In the case of the complex of 1,3,5-tris­[(1H-indazol-1-yl)meth­yl]-2,4,6-tri­ethyl­benzene (QIDVAD; Schulze et al., 2018 ▸), the asymmetric unit contains four receptor mol­ecules, four NH4PF6, one water and two methanol mol­ecules. As a result, complexes are formed, the structures of which differ strongly from that of the title complex.

Synthesis and crystallization

To a solution of 4-methyl-1H-indazole (500 mg, 3.78 mmol) in di­methyl­formamide (9.0 mL) sodium hydroxide (152 mg, 3.78 mmol) was added and the suspension was stirred at room temperature for 30 minutes. Then 1,3,5-tris­(bromo­meth­yl)-2,4,6-tri­ethyl­benzene (418 mg, 0.95 mmol) was added and the mixture stirred at 343 K for 24 h. After cooling to room temperature, the reaction mixture was poured into ice–water (55 mL). The precipitate was filtered off, washed with a little ice–water and dried under reduced pressure. The crude mixture, containing the desired product as well as two other tri­ethyl­benzene derivatives and the unreacted 4-methyl-1H-indazole, was separated chromatographically. The first flash chromatography (SiO2; gradient, hexa­ne/ethyl acetate 4:1 to 3:2, v/v) allowed the isolation of the by-products 2,4,6-tri­ethyl-1,3-bis­[(4-methyl-1H-indazol-1-yl)meth­yl]-5[(4-methyl-2H-indazol-2-yl)meth­yl]­benzene and 2,4,6-tri­ethyl-1,3-bis­[(4-methyl-2H-indazol-2-yl)meth­yl]-5[(4-methyl-1H-indazol-1-yl]meth­yl]­benzene, while the second one (SiO2; gradient, toluene/ethyl acetate 16:1 to 4:1, v/v) enabled the removal of 4-methyl-1H-indazole. After crystallization from hexa­ne/ethyl acetate (2:1, v/v) the title compound was obtained as colourless crystals (110 mg, 20%); m.p. 427–429 K. 1H NMR (500 MHz, CDCl3, ppm) δ = 0.80 (t, J = 7.5 Hz, 9H), 2.58 (s, 9H), 2.89 (q, J = 7.5 Hz, 6H), 5.63 (s, 6H), 6.87 (dt, J = 7.0/1.0 Hz, 3H), 7.03 (dd, J = 8.5/1.0 Hz, 3H), 7.12 (dd, J = 8.5/7.0 Hz, 3H), 8.01 (d, J = 1.0 Hz, 3H). 13C NMR (125 MHz, CDCl3, ppm) δ = 14.7, 18.6, 23.8, 47.6, 107.0, 120.5, 124.8, 126.5, 130.6, 131.4, 132.0, 139.6, 145.7.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The hydrogen atoms were positioned geometrically and refined isotropically using the riding model with C—H = 0.95–0.99 Å and U iso(H) = 1.2 or 1.5U eq(C). The hydrogen atoms of the ammonium ions were located in a difference-Fourier map and the N—H bond lengths refined to a target value of 0.90 Å. The crystal studied was refined as a two-component twin.

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.
