摘要：

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(2)dtc)X (X = Cl-, Br-) and Cu(Et(2)dtc)(+) ... Y- (Y- = ClO4-, NO,) in chloroalkane/alcohol solutions, where chloroalkane = CCl4, CHCl3 or CH2Cl2 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. (C) 1998 Elsevier Science B.V. All rights reserved.
