Crystal structures of two nickel compounds comprising neutral NiII hydrazone complexes and di-carb-oxy-lic acids.

Two isostructural NiII compounds, bis-{N-[1-(pyridin-2-yl-κN)eth-ylidene]pyridine-4-carbohydrazonato-κ2N',O}nickel(II)-2,5-di-chloro-terephthalic acid (1/1), [Ni(C13H11N4O)2](C8H4Cl2O4), and bis-{N-[1-(pyridin-2-yl-κN)eth-ylidene]pyridine-4-carbohydrazonato-κ2N',O}nickel(II)-2,5-di-bromo-terephthalic acid (1/1), [Ni(C13H11N4O)2](C8H4Br2O4), were synthesized and their crystal structures determined. The pair of N,N',O-tridentate N-[1-(pyridin-2-yl-κN)eth-yl]pyridine-4-carbohydrazonate L ligands result in a cis-NiO2N4 octa-hedral coordination sphere for the metal ions. The asymmetric units consist of two half-mol-ecules of the di-carb-oxy-lic acids, which are completed by crystallographic inversion symmetry. In the respective crystals, the 2,5-di-chloro-terephthalic acid (H2Cl2TPA, 1-Cl) mol-ecules form zigzag hydrogen-bonded chains with the [Ni(L)2] mol-ecules, with the hydrogen-bond distances in 1-Br slightly longer than those in 1-Cl. The packing is consolidated by aromatic π-π stacking between the di-carb-oxy-lic acid mol-ecules and terminal pyridine rings in [Ni(L)2] and short halogen-halogen inter-actions are also observed. The qualitative prediction of the H-atom position from the C-N-C angles of the terminal pyridine rings in L and the C-O distances in the carboxyl groups show that 1-Cl and 1-Br are co-crystals rather than salts.

Chemical context

Metal complexes based on 2-acetyl­pyridine isonicotinoyl­hydrazone (HL) have attracted considerable attention for the construction of supra­molecular materials (Servati Gargari et al., 2015 ▸; Valipour et al., 2016 ▸) and as functional complexes for applications in various biochemical fields (Ababei et al., 2012 ▸; Chang, Jia, Xu, Xu et al., 2015 ▸; Chang, Jia, Xu, Wu et al., 2015 ▸). Moreover, the precursors of HLs and related hydrazone ligands have been used in the design of complexes stabilized by strong hydrogen bonds (Lemmerer et al., 2010 ▸; Grobelny et al., 2011 ▸; Aakeröy et al., 2012 ▸; Cherukuvada & Nangia, 2012 ▸; Aitipamula et al., 2009 ▸) and spin-crossover complexes (Hill et al., 2010 ▸; Zhang et al., 2010 ▸). Thus, it is possible that metal complexes with HL ligands could be applied in the design of various functional materials. We have reported spin-crossover compounds consisting of [Fe(L)2] and H2Cl2TPA, and of [Fe(L)2] and H2Br2TPA (H2Cl2TPA = 2,5-dichloroterephtalic acid, H2Br2TPA = 2,5-di­bromo­terephthalic acid), and it was observed that a one-dimensional zigzag hydrogen-bonding network involving short hydrogen bonds was formed between the [Fe(L)2] mol­ecules and di­carb­oxy­lic acids (Nakanishi & Sato, 2016 ▸). In this study, we present the crystal structures of the analogous NiII complexes, [Ni(L)2](H2Cl2TPA) (1-Cl) and [Ni(L)2)](H2Br2TPA) (1-Br).

Structural commentary

The mol­ecular structures of 1-Cl and 1-Br are displayed in Figs. 1 ▸ and 2 ▸, respectively. The crystal structures of 1-Cl and 1-Br are isostructural with each other: the asymmetric unit comprises one [Ni(L)2] mol­ecule and two half di­carb­oxy­lic acid mol­ecules, which are completed by crystallographic inversion symmetry. These are hereafter designated as (H2 X 2TPA) with O3 and O4 and (H2 X 2TPA) with O5 and O6 (X = Br, Cl). The pair of N,N′,O-tridentate L ligands generate a cis-NiO2N4 octa­hedron in each case.

Unfortunately, the hydrogen-atom positions in the hydrogen-bonding network could not be determined from difference Fourier maps. However, the positions of hydrogen atoms involved in hydrogen bonds could be predicted qualitatively from the C—N—C angles of the terminal pyridine ring in L and the C—O bond lengths of the carboxyl group in H2 X 2TPA. The coordination distances and angles related to the hydrogen-bonding network are listed in Table 1 ▸. The C13–N4–C11 and C24–N8–C26 bond angles in 1-Cl are 117.4 (2)° and 118.8 (2)°, respectively, and these are categorized as being part of a non-protonated pyridine ring (Bis & Zaworotko, 2005 ▸). Moreover, the C34—O3 and C27—O5 distances in 1-Cl are 1.316 (3) and 1.306 (3) Å, respectively, and these clearly correspond to a protonated carb­oxy­lic acid (Bis & Zaworotko, 2005 ▸). These results indicate that the hydrogen atoms involved in hydrogen bonds are mainly located on the H2 X 2TPA side. Therefore, it could be concluded that 1-Cl is a co-crystal, comprising neutral [Ni(L)2] complexes and H2Cl2TPA mol­ecules, rather than a salt. The same conclusion can be drawn concerning 1-Br (Table 2 ▸).

Supra­molecular features

The mol­ecular arrangement in the hydrogen-bonding network in 1-Cl is shown in Fig. 3 ▸. It was confirmed that [Ni(L)2] forms a one-dimensional zigzag hydrogen-bonding network with H2 X 2TPA via the terminal py ring in L. In addition, in each case the two H2 X 2TPA mol­ecules can be differentiated from one another in terms of the hydrogen-bond distance in the hydrogen-bonding chain; the (H2 X 2TPA) mol­ecule forms a long hydrogen bond [N4⋯O3 = 2.679 (3) Å] and the (H2 X 2TPA) mol­ecule forms a shorter hydrogen bond [N8⋯O5 = 2.547 (3) Å] (Table 3 ▸). The carboxyl groups in each H2 X 2TPA mol­ecule are related by inversion, hence exhibiting the same hydrogen bonds at each end of the mol­ecule (Fig. 3 ▸). The hydrogen-bond distance N8⋯O5 [2.547 (3) Å] is relatively short, but not comparable with the distances observed in the organic compounds that exhibit proton migration (Steiner et al., 2001 ▸; Cowan et al., 2003 ▸, 2005 ▸). The hydrogen bond distances N4⋯O3 and N8⋯O5 in 1-Br are 2.706 (4) and 2.557 (4) Å (Table 4 ▸), respectively, and these are clearly longer than the equivalent bonds in 1-Cl; the same tendency was confirmed when comparing [Fe(L)2](H2Cl2TPA) and [Fe(L)2](H2Br2TPA) (Nakanishi & Sato, 2016 ▸).

Another inter­molecular inter­action in each H2 X 2TPA, a π–π inter­action, is found between the (H2 X 2TPA) mol­ecule and the terminal pyridine ring in [Ni(L)2]. Furthermore, the (H2 X 2TPA) mol­ecules form halogen–halogen inter­actions with adjacent (H2 X 2TPA) mol­ecules [1-Cl: Cl1⋯Cl1i = 3.435 (1) Å, C30–Cl1⋯Cl1i = 129.64 (9)°; 1-Br: Br1⋯Br1 = 3.5240 (8) Å, C30—Br1⋯Br1i = 125.3 (1)°; symmetry code: (i) 1 – x, −1 – y, –z] as observed in an overview of the crystal structure (Fig. 4 ▸).

Synthesis and crystallization

[Ni(L)2](H2Cl2TPA) (1-Cl)

HL was synthesized according to the published procedure (Ababei et al., 2011 ▸). HL (48 mg, 0.20 mmol) was dissolved in methanol (40 ml); then, NiCl2·6H2O (24 mg, 0.10 mmol) was added to the solution. Following this, H2Cl2TPA (24 mg, 0.10 mmol) was added to the solution. The mixture was stirred for 30 s. Subsequently, the solution was evaporated in air over a period of several days. Plate-shaped brown crystals were obtained.

[Ni(L)2](H2Br2TPA) (1-Br)

The synthesis procedure for 1-Br is similar to that for 1-Cl, except for the use of H2Br2TPA instead of H2Cl2TPA. Plate-shaped brown crystals were obtained.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 5 ▸. The hydrogen atoms connected to the carbon atom were treated using a riding model: C—H (aromatic) = 0.96 Å and C—H (meth­yl) = 0.98 Å. The hydrogen atoms involved in hydrogen bonds were also treated as riding with O—H = 0.84 Å.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 sigma(F2) is used only for calculating R-factor (gt).
