Thermodynamics of metal-ligand bond formation. XXII. Zinc(II) and cadmium(II) dialkyldithiocarbamates

Abstract

Thermodynamic data are reported for dimerization of dialkyldithiocarbamates, (R₂NCS₂)₂Cd, and for addition of heterocyclic bases to (R₂NCS₂)₂Cd and (R₂NCS₂)₂Zn in benzene solution. Enthalpies of reaction are comparable to those of corresponding dithiophosphates, but adduct formation and dimerization constants are smaller and the dithiocarbamates add only one molecule of base. Though probably bidentate, 2,2'-bipyridine forms less stable adducts with (R₂NCS₂)₂Zn than does pyridine.
