【Abstract】 Dissymmetrical oxamido-bridged heterobinuclear [Cu(oxbe)Mn(phen) 2]ClO 4·3H 2O complex has been synthesized and characterized by means of elemental analysis, IR, EPR, and electronic spectra and magnetic susceptibility, where oxbe is -3 valent anion of dissymmetrical ligand N-benzoato-N′-(2-aminoethyl)oxamido, phen=1,10-phenanthroline. Results indicate the title complex has an extended oxamido-bridged structure, consisting of planar Cu(Ⅱ) and octahedral Mn(Ⅱ) ions. Variable-temperature(5～300K) magnetic susceptibility measurements were recorded for the title complex. The exchange integral,J=-29 3cm -1,indicating a weak antiferromagnetic superexchange interaction between two metal ions.更多还原
