The e.s.r. spectra of seven copper(II) dithiocarbamates have been recorded in chloroform-ethanol mixtures at room temperature and at 113 K.It has been found that the addition of a range of salts to these dithiocarbamates destroys the complex forming a mixed-ligand complex, , with a new e.s.r. spectrum.When X is Cl or Br the additional interaction of the unpaired electron with a single halogen nucleus is observed.The complex forms a dipole-dipole coupled dimer and a computer simulation of the ΔMs = 2 absorption of this dimer has been obtained.
KINETICS AND MECHANISM OF FORMATION OF COPPER (II) DITHIOCARBAMATES IN ACETONITRILE.

Kinetics of formation of copper (II) bis-dithiocarbamates in a system, containing copper acetate, diethyl- or dibenzylamine, and carbon disulfide were studied in acetonitrile. Reactions orders in amine (second) and carbon disulfide (first) were determined. Rate constants were determined and it was found that they increase upon addition of pyridine and decrease with an increase in temperature, copper acetate concentration, and upon going from diethyl- to dibenzylamine. The obtained results were explained in the framework of a mechanism, according to which a charge-transfer complex of the amine yields carbon disulfide type is formed at the first stage. Then this complex reacts at the limiting stage with a second amine molecule to give dithiocarbamate ion, which forms rapidly a stable complex with copper ion.
