M(nmedtc)2 and M(padtc)2 (where nmedtc- = N-methyl-N-ethanol-dithiocarbamate anion; padtc = N,N1-(iminodiethylene)bisphthalimidedithiocarbamate anion; M = Zn(II), Cd(II), Hg(II)) complexes were synthesized and characterized. Zinc and cadmium complexes are tetra-hedral. Splitting of the vC-S band in Cd(nmedtc)2 indicates anisobidentate coordination of the ligand. The mercury analogue is polymeric. Thioureide vC-N bands for Cd(nmedtc)2 and Hg(padtc)2 appear at relatively low energy due to the large sizes of the cadmium and mercury ions in comparison with zinc. Thermal studies have been carried out. Unit cell constants of Zn(deadtc)2 are a = 29.017(2)Å, b = 8.611(4)Å, c= 14.045(2) Å, β= 103.2(1)°, space group C2/c. The coordination polyhedron is a distorted trigonal bipyramid. Thioureide C-N is 1.489(5) Å, which is significantly longer than observed in the corresponding diethyl analogue (1.325(9) Å). Zn-Zn' is 3.485(3) Å compared to 3.546(3) Å observed in the diethyl analogue. |
