A mixed-ligand complex ZnPhen(n-BuOCS2)2 has been synthesized. The structure of the compound was solved by X-ray diffractometry (X8 APEX diffractometer, MoK α radiation, 4254 F hkl , R = 0.0448). Triclinic crystals with the parameters a = 9.4464(3) Å, b = 11.0279(4) Å, c = 13.6528(6) Å;α = 106.940(1)°, β = 98.382(1)°, γ = 106.347(1)°; V = 1264.72(8) Å3; Z = 2, space group 1. P1¯. The structure consists of discrete mononuclear molecules. The polyhedron of the Zn atom is a trigonal bipyramid N2S3 formed by coordination of the N atoms of the bidentate Phen molecules and the sulfur atoms of the monodentate and cyclic bidentate xanthate ligands. Dimer assemblies are formed in the structure due to π-π interactions of Phen molecules.
