Reactivity of Barium Dithiocarbamate Derivatives of Glycine and Alanine Towards Metal Acetylacetonate and Cobaloxime Complexes

Abstract

A number of mixed ligand complexes of the general formulae Ba[M(acac)₂ (Rdtc)], [M′(acac)_n]₂ (Rdtc) (Rdtc = glycinyl- or L-alaninyldithiocarbamate, acac = acetylacetonate, M = Co⁺², Ni²⁺ or Cu²⁺, M′ = V0²⁺ or Fe³⁺, n=l or 2) and [Co(DH)(DH₂)]-(L-alandtc) (DH=dimethylglyoximate) have been synthesised The characterisation of the compounds was achieved on the basis of elemental analyses and IR and electronic spectra; the thermal behaviour of the complexes was also studied. An octahedral structure around the central metal atoms is proposed. Vanadium(IV) and iron(III) complexes are supposed to be dimeric, with the glycinyl- and L-alaninyldithiocarbamates acting as a bridge.
