The synthesis,the spectral and structural characterization of two new compounds of the series [Cu(sal)(AA)(ClO_4)] (sal=anion of the salicylaldehyde,AA=4,4'-dimethyl-2,2'-bispyridil and 2,2'-bispyrimidine)

摘要

Two new mononuclear complexes belonging to the series [Cu(sal)(AA)(ClO_4)] (sal=salicylaldehydate,AA-aromatic diamines) have been obtained and crystallographically characterized.In the two compounds,[Cu(sal)(Me -bipy)(ClO_4)] and [Cu(sal)(bipym)(ClO_4)] (Me_2-bipy=4,4'-dimethyl-2,2'-bipyridine;bipym=2,2'-bipyrimidine),the copper(II) ions exhibit a square pyramidal geometry with the chelatic ligands forming the basal plane and the perclorate onion coordinated in the apical position.The spectral properties of the two compounds were investigated in UV,visible and 1R domains.
