摘要：
Zn(II), Cd(II), and Hg(II) complexes of alkyl-aryl dithiocarbamate formulated as ZnL1L2 (1), CdL1L2 (2), and HgL1L2(3) have been synthesized and characterized. X-ray crystallographic analysis shows that the Hg(II) complex, [(C6H5N(et)CS2)Hg(C6H5N(butyl)CS2)] is four coordinate with distorted tetrahedral geometry. Distortions from the regular tetrahedral geometry are attributed to the restricted bite angles of the dithiocarbamate ligand. The spectroscopic analyses confirmed the proposed four coordinate geometry for the complexes in which the metal ions are coordinated to two molecules of the ligands through the S-atoms. X-ray analysis of the mercury complex revealed a compositional disorder between the alkyl groups at certain carbon positions.
