Abstract top

In the title complex, [Ni(C9H5O6)2(C11H10N4)2]·8H2O, the NiII ion exhibits site symmetry 2. It has a distorted octahedral coordination defined by two N atoms from two symmetry-related 1-[(1H-benzimidazol-1-yl)methyl]-1H-imidazole ligands and four O atoms from two symmetry-related 3,5-dicarboxybenzoate anions. In the crystal, the complex molecules and solvent water molecules are linked via O-H...O, O-H...N and N-H...O hydrogen bonds, forming a three-dimensional structure. There are also a number of C-H...O interactions present.

Comment top

Since NiII ions are able to coordinate simultaneously to both oxygen and nitrogen containing ligands the final products can exhibit attractive structures and useful functional properties. A great number of NiII complexes containing both aromatic carboxylates and N-heterocyclic ligands have been reported (Hu et al., 2011; Xu et al., 2010). In order to further explore such compounds with possibly new structures, we selected 1-((1H-benzimidazol-1-yl)methyl)-1H-imidazole and 1,3,5-benzenetricarboxylic acid as ligands to self-assemble with Ni(NO3)2 and obtained the title complex. The crystal structure of which is reported on herein.

As shown in Fig. 1, the NiII ion is located on a two-fold rotation axis. Each NiII ion features a distorted octahedral geometry and is hexacoordinated by four O atoms from two symmetry related 1,3,5-dicarboxybenzoate anions, in which carboxylate groups coordinate to the NiII ion in the chelating mode, and by two N atoms from two symmetry related 1-((1H-benzimidazol-1-yl)methyl)- 1H-imidazole ligands, which coordinate to NiII ion in a monodentate mode. Atoms O2, O2A, O1A, N1A, and Ni1 are nearly co-planar (the mean deviation from the plane is 0.0726 (12) Å), while atom O1 and N1 are located in the apical positions.

In the crystal, a series of O—H···O, O—H···N, and N—H···O hydrogen bonds linking, solvent water to water molecules, solvent water molecules and carboxylate O atoms, carboxyl groups and benzimidazole N atoms, and benzimidazole units and solvent water molecules, consolidate the crystal packing forming a three-dimensional structure (Table 1). There are also a number of C-H···O interactions present (Table 1).

Experimental top

A mixture of Ni(NO3)2 (0.1 mmol), 1-((1H-benzimidazol-1-yl)methyl)-1H-imidazole (0.1 mmol), 1,3,5-benzenetricarboxylic acid (0.1 mmol) and water (10 ml) was placed in a 25 ml Teflon-lined stainless steel vessel and heated at 373 K for 72 h, then cooled to room temperature. Green crystals were obtained from the filtrate and dried in air.

Refinement top

The C-bound H atoms were positioned geometrically and refined as riding atom: C-H = 0.93 (aromatic) Å and 0.97 (CH2) Å. The water and NH H atoms were located in difference Fourier maps. In the final cycles of refinement they were included in calculated positions and refined as riding atoms: N-H = 0.86 Å and O-H = 0.82 (OH) Å and O-H = 0.85 (H2O) Å. All H atoms were refined with Uiso(H) = 1.2Ueq(C,N,O).

Special details top

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 > 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.
