Bis{1-[(1H-benzimidazol-1-yl)methyl]-1H-imidazole-κN³}bis(3,5-dicarboxybenzoato-κ²O¹,O^1′)nickel(II) octahydrate

Abstract

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.
