The effect of chloroalkane/alcohol solvent composition on the photochemical properties of copper(II) dithiocarbamate mixed-ligand complexes. EPR study

The EPR technics has been used to study the effect of solvent composition on the photochemical conversion of Cu(II) dithiocarbamate mixed-ligand complexes Cu(Et 2dtc)X (X=Cl −, Br −) and Cu(Et 2dtc) +…Y − (Y −=ClO 4 −, NO 3 −) in chloroalkane/alcohol solutions, where chloroalkane=CCl 4, CHCl 3 or CH...

Summary:The EPR technics has been used to study the effect of solvent composition on the photochemical conversion of Cu(II) dithiocarbamate mixed-ligand complexes Cu(Et 2dtc)X (X=Cl −, Br −) and Cu(Et 2dtc) +…Y − (Y −=ClO 4 −, NO 3 −) in chloroalkane/alcohol solutions, where chloroalkane=CCl 4, CHCl 3 or CH 2Cl 2 and alcohol=MeOH, EtOH, i-PrOH or i-BuOH. The obtained results allow to get some insight into the behaviour of the mixed-ligand complexes towards the halogen donation power of chloroalkanes and the co-ordination abilities of alcohols. The paper deals with the nature of the complexes obtained as intermediate products of photolysis.
