A mixed-ligand complex Zn(Phen)(S2COC4H9-i)2 was synthesized. The single crystals of the complex were studied by X-ray diffractometry. The crystals are orthorhombic, a = 20.053(2), b = 19.272(2), c = 13.203(1) A, Vcdl = 5102.5(8) A3, space group Pcab, Z = 8, dcalc = 1.416 g/cm3, R = 0.059. The structure consists of monomeric molecules in which the coordination polyhedron of the central Zn atom is a distorted octahedron (CN = 6). An analysis of molecular packing and intermolecular distances showed that the molecules related by the symmetry center are involved in pronounced intermolecular interactions.
