Zn (II), Cd (II), and Hg (II) complexes of N-methyl-N-phenyl dithiocarbamate (L1) and N-butyl- N-phenyl dithiocarbamate (L2) formulated as ML1L2 have been synthesized and characterized by elemental analysis, FT–IR, 1H-and 13C-NMR spectroscopic techniques. Single-crystal X-ray structures of the Zn (II) and Hg (II) complexes are also reported. X-ray crystal structures revealed that in the zinc (II) complex, the dithiocarbamate is chelating ...
