Abstract: By phys.-chem. analyses of solns. of CuCl₂-[LiClO₄ + 3H₂O], [NaClO₄ + H₂O]-Me₂CO, the formation of chloroperchlorate-copper(II) complexes was detd. It was assumed that in the acetone soln. there is an existence of multi-Cu(II) complexes with ClO₄^- groups acting as bridge ligands. The formation of nitrato-Co(II) and Cl^--nitrato-Co(II) complexes was detd. The entrance of the NO₈^- group into the inner sphere of heterogeneous Cl^--nitrato-Co(II) complexes is not only shown by shifting of max. absorption bands, typical for the system CoCl₂-Me₂CO, but also by a formation of a new absorption band. From the deformation of the absorption curve in the system CoCl₂-Me₂CO, after introducting ClO₄^- into the soln., it was detd. that in acetone chloro-perchlorate-Co(II) complexes form.
