Crystal Structure of the Mixed-Ligand Compound [HgPhen{(C2H5)2NCS2}2] and the Character of Intermolecular Interactions in [MPhen{(C2H5)2NCS2}2] (M = Zn, Cd, Hg)

Abstract

Single crystals of the mixed-ligand complex compound [HgPhen(Et2NCS2)2] were obtained. The crystal structure of the compound was determined by X-ray diffraction analysis (CAD-4 diffractometer, Mo $$K_\alpha $$ radiation, 3640 F hkl , R = 0.0280). Triclinic crystals with cell parameters a = 10.308(2), b = 11.171(3), c = 11.552(2) A, α = 94.16(2), β = 96.66(1), γ = 105.17(2)°, V = 1267.8(5) A3, Z = 2, d calc = 1.774 g/cm3, space group $$P\bar 1$$ . The structure is composed of discrete monomer molecules. The coordination polyhedron of the Hg atom is a distorted octahedron formed by four S atoms of the two cyclic bidentate Et2 $$NCS_{2^ - } $$ ligands and two N atoms of the cyclic bidentate Phen ligand. The character of interactions between [MPhen(Et2NCS2)2] (M = Zn, Cd, Hg) molecules and their packing in the structure are considered.
