Abstract
In the title compound, [Cu(C14H9N2O2)2]·2H2O, the Cu(II) ion lies on a centre of symmetry and is four-coordinated by two N atoms and two O atoms from two 2-(1H-benzimidazol-2-yl)benzoate ligands in a square-planar environment. The benzimidazol and benzyl rings form a dihedral angle of 42.8 (5)°. The molecule contains two H-bonded carboxyl O acceptors and two H-bonded N—H donors in the benzimidazol groups, which interact with two symmetry-related uncoordinated water molecules so that neighboring molecular units are linked by (O—H)water⋯Ocarboxyl hydrogen bonds with an R 2 4(8) graph-set motif, generating a helical chain in the a-axis direction. These chains are, in turn, interconnected by (N—H)benzimidazol⋯Owater hydrogen bonds, forming a three-dimensional supramolecular network.
