Synthesis and Magnetism of Novel Copper (Ⅱ)-Manganese (Ⅱ) and Copper (Ⅱ)-Cobalt (Ⅱ) Complexes Containing Phenoxy-Bridge

Abstract

Abstract: New binuclear complexes, [Cu(samen)Mn(NO_2^-Phen)₂] (1), [Cu(sampn)Mn(NO_2^-Phen)₂] (2) and [Cu(samen)Co(terp)] (3) were synthesized,where samen_4-, sampn_4-, NO_2^-Phen and terp denote N, N'-ethylenedisalicylamidate anion, N,N'-1,2-propanedissalicylamidate anion, 5-nitro-l,10-phenanthroline and terpyridyl respectively. The complexes were characterized with variable temperature magnetic susceptibility. The exchange integral, J ,was found to be -63 cm^-1(1), - 65 cm^-1(2) and -7. 68 cm^-1(3), indicating that antiferromagnetic spin exchange interaction operates among the metal ions.

Key words: Phenoxy-brⅡdge, Copper( Ⅱ )-menganese( Ⅱ ), Copper( Ⅱ )-Cobalt( Ⅱ ), Magnetism
