In the title compound, [Ni(C7H12N2)4(H2O)2]Cl2, the nickel(II) ion has a distorted octa­hedral coordination environment. It is surrounded by three N atoms and one O atom occupying the equatorial plane, and one N and one O atom in the axial positions. The imidazole ring systems are inclined to one another with dihedral angles varying between 38.3 (4) and 74.1 (4)°. In the crystal, mol­ecules are linked via O—H⋯Cl hydrogen bonds involving one Cl− anion and the water mol­ecule in the equatorial plane, forming an inversion dimer-like arrangement. The water mol­ecule in the axial position is hydrogen-bonded to both Cl− anions. There are also a number of C—H⋯Cl hydrogen bonds present, forming a three-dimensional structure. All four alkyl chains are disordered over two positions with refined occupancy ratios of 0.395 (15):0.605 (15), 0.658 (14):0.342 (14), 0.332 (11):0.668 (11) and 0.622 (12):0.378 (12).

Comment top

Imidazoles have been reported to serve as useful building blocks for the synthesis of diverse classes of bioactive molecules. In addition, imidazole-containing compounds exhibit a wide spectrum of pharmaceutical properties such as pesticides, fungicides, antibacterial, anti-inflammatory, anti-tubercular, anti-diabetic, antimalarial and antitumour (Roman et al., 2007; Nanterment et al., 2004; Congiu et al., 2008; Venkatesan et al., 2008; Bhatnagar et al., 2011; Puratchikody & Doble 2007).

Knowledge of the detailed coordination behaviour of imidazoles and their limitation in the possible use in complexes with specific catalytic activity is of great current importance. Imidazoles, namely 1,3-diazacyclopenta-2,4-diene and its derivatives, have found a wide range of applications in coordination chemistry because of their multiple coordination modes as ligands to metal ions and for the construction of novel metal–organic frameworks (Huang et al., 2008, 2011).

The chemistry of imidazole occupies an extremely important position within the family of five-membered heterocyclic compounds. Synthesis of imidazole derivatives has attracted great interest in recent years due to their broad spectrum of biological activities (Gaonkar et al., 2009). This paper describes the synthesis and crystal structure of the nickel(II) complex of the imidazole ligand 1-butyl-1H-imidazole.

The molecular structure of the title compound is illustrated in Fig. 1. The nickel(II) ion has a distorted octahedral coordination environment. It is surrounded by four N and two O atoms; an N and an O atom are in the axial positions, and the other three N atoms and an O atom are in the equatorial plane. The imidazole ring (N1/N2/C1–C3) makes dihedral angles of 44.7 (4)°, 38.3 (4)° and 74.1 (4)° with the other three imidazole rings (N3/N4/C4–C6), (N5/N6/C7–C9) and (N7/N8/C10–C12), respectively.

In the crystal, molecules are linked via O—H···Cl hydrogen bonds, involving one Cl- anion (Cl2) and the water molecule (O2) in the equatorial plane, to form an inversion dimer-like arrangement. The water molecule in the axial position (O1) is hydrogen-bonded to both Cl- anions. There are a number of C—H···Cl interactions present forming a three-dimensional structure. Details are given in Table 1.

Experimental top

NiCl2.6H2O (6.0 g) was dissolved in warm ethanol (3 ml). The solution was cooled in ice while adding slowly a solution of 1-butylimidazole (5.0 g in 5.6 ml EtOH); the reaction is quite exothermic. Cold ethanol (15 ml) was then added to initiate crystallization. The colourless crystalline solid was filtered and kept cold for 10 min then washed with two 5 ml portions of ethanol and dried in air.

Refinement top

Thy water H atoms were located in a difference Fourier map and freely refined. The C-bound H atoms were included in calculated positions and treated as riding atoms: C—H = 0.93–0.97 Å with Uiso(H) = 1.5Ueq(C) for methyl and = 1.2Ueq(C) for other H atoms. The four alkyl chains are disordered over two positions with refined occupancy ratios of 0.395 (15):0.605 (15); 0.658 (14):0.342 (14); 0.332 (11):0.668 (11); 0.622 (12):0.378 (12).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance–covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
