| Abstract: | Preparation and Some Characteristics of Copper(I)-Copper(II) Selenocyanates From the system Cu2+-H2O-en-SeCN-in dependence on the conditions two new complexes have been prepared: Cu3en2(SeCN)(CN)3· H2O(I) and Cu3en2(SeCN)2(CN)2· H2O(II). They were studied by the methods of infra-red and EPR spectra as well as by those of X-ray diffraction. It has been found that Cu2+ is coordinated in these complexes with two molecules of ethylene diamine and one molecule water. The anion ligands have a bridging function and coordinate the copper(I). The EPR spectra show that the two complexes exhibit around the atom Cu2+ have different ligand field symmetry. For complex (I) it is a typically axial spectrum with two values of the gfactor g⊥? 2.18 and g⊥? 2.05 while complex (II) has an asymmetrical isotropic spectrum with one g-factor value only g⊥? 2.07. |
