Features of Formation of Mononuclear and Binuclear Copper(II) Complexes with 2,2'-Bipyridyl and closo-Decaborate Anion
The copper(I) complexation reaction with 2,2'-bipyridyl in the presence of salts of the closo -deca-borate anion has been studied in air in organic solvents (1,2-dichloroethane and DMF). It has been found that, as a result of the redox reaction, copper(II) coordination compounds with the [B 10...

Summary: | The copper(I) complexation reaction with 2,2'-bipyridyl in the presence of salts of the
closo
-deca-borate anion has been studied in air in organic solvents (1,2-dichloroethane and DMF). It has been found that, as a result of the redox reaction, copper(II) coordination compounds with the [B
