Chemical Processes in Systems CuI(CuII)/L/[B12H12]2-/solv (L = bipy, phen; solv = CH3CN, DMF, and CH2I2)

Processes proceeding in the Cu-I(Cu-II)/L/(L = bipy, phen) systems in the presence of the [B12H12](2-) anion, which has the lowest reduction ability among the boron cluster anions [B (n) H (n) ](2-) (n = 6, 10, 12), have been studied. It has been found that the preparation of Cu-I and heterovalent Cu-I/Cu-II complexes with azaheterocyclic ligands and the [B12H12](2-)anion requires the Cu-II reduction process to be initiated. To minimize the redox process in the Cu-I/L/[B12H12](2-) system, redox-active starting components have been added to the reaction system. Mono- and polynuclear copper complexes with various composition and structures have been isolated as a result of redox reactions proceeding in the Cu-I(Cu-II)/L/[B12H12](2-)/solv (L = bipy, phen; solv = CH3CN, DMF, CH2I2) systems.
