Complexes of Tertiary Thioamides: Part III^†: Complexes of Dimethyl-Thioacetamide with Co(II), Pd(II), Zn(II), Cd(II) and Hg(II)

Complexes of dimethyl-thioacetamide (DMTA or L) with Co(II), Pd(II), Zn(II), Cd(II) and Hq(II) have been prepared and investigated by conductivity measurements, and by electronic, infrared and Raman spectroscopy. mL₂Cl₂ (M=Co, Zn, Hg), ML₂I₂ (M=Co, Zn, Cd, Hg) and [ML₄] (ClO₄)₂ (M=Co, Zn, Cd) complexes are shown to be tetrahedral. CdLcl₂ is polymeric, but a definite structure could not be assigned. Pd(II) forms planar cis-PdL₂Cl₂, trans-PdL₂I₂ and [PdL₄] (ClO₄)₂. DMTA acts in all cases as a monodentate sulphur donor ligand.
