چکیده
In the title compound, [Cu(C(14)H(9)N(2)O(2))(2)]·2H(2)O, 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 mol-ecule contains two H-bonded carboxyl O acceptors and two H-bonded N-H donors in the benzimidazol groups, which inter-act with two symmetry-related uncoordinated water mol-ecules so that neighboring mol-ecular units are linked by (O-H)(water)⋯O(carbox-yl) 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, inter-connected by (N-H)(benzimidazol)⋯O(water) hydrogen bonds, forming a three-dimensional supra-molecular network.
