In the title complex, [Ni(C15H11ClN2O3)(C3H4N2)], the NiII ion is coordinated by a phenolate O, hydrazine N and carbonyl O atom from the hydrazone ligand and by an N atom from the imidazole molecule, forming a distorted square-planar geometry. Intermolecular N—H⋯N hydrogen bonds link neighboring molecules into extended chains parallel to [100].

The hydrazone ligand was prepared by the reaction of salicylaldehyde and 4-chloro-phenoxyacetylhydrazine in a molar ratio of 1:1 under reflux in ethanol for 2 h. The yellow product obtained on cooling was recrystallized from methanol. Salicylaldehyde 4-chloro-phenoxyacetylhydrazone (1 mmol), [Ni(OAc)2].4H2O (1 mmol), imidazole (1 mmol), N,N-dimethylformamide (5 ml), and methanol (10 ml) were stirred for 2 h. The solution was filtered and allowed to stand at room temperature for one week, and red crystals of complex (I) were obtained.
All H atoms were placed in idealized positions and treated as riding with N—H = 0.86 Å, C—H = 0.93–0.97Å and Uiso(H) = 1.2Ueq(C/N).

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

Hydrazones are of interest owing to their capacity for chelating to transition (Sur et al., 1993; Sun et al., 2005), lanthanide (Ma et al., 1989) and main group (Liu & Gao 1998) metals. Here we report the crystal structure of the title complex, (I) (Fig. 1). The Ni(II) ion exists in a square-planar N2O2 coordination geometry defined by the phenolate O1, hydrazine N1, and carbonyl O2 atom of the hydrazone ligand, and N3 atom from the 1H-imidazole molecule. The hydrazone ligand in the title complex is distorted, the dihedral angle between the two phenyl rings being 50.56 (9)°. The corresponding dihedral angle is about 87° in the complex [Co(C15H12N2O3)(C5H7O2)(C3H7NO)] (Chen & Liu, 2006) with the ligand of salicylaldehyde phenoxyacylhydrazone. In the title complex, an extended one-dimensional chain structure is formed via intermolecular hydrogen bonds between the 1H-imidazole N—H groups and the uncoordinated N-atom of the hydrazone ligand (Fig. 2). The N4···N2(A) distance and the N4—H···N2(A) angle are 2.916 (3) Å and 171.92°, respectively [Symmetry code: (A) x - 1/2, y, -z + 1/2].
