| Abstract: Two new binuclear complexes containing bichloro-bridging ligand were synthesized,namely M2(BZA)2C12·xH2O(BZA=anion of benzoylacetone in enol form;M=Ni,x=l;M=Zn,x=2).The complexes have been characterized by elemental analyses,IR,electronic spectra,susceptibility.The variable-temperature magnetic susceptibilities of Ni(Ⅱ) complexwere measured (4-300K),and the susceptibility equation derived from the spin HamiltonianH=-2JS1·S2.The exchange integral,J,was found to be equal to -1.36cm-1.This indicates aweek antiferromagnetic spin exchange interaction between Ni(Ⅱ)-Ni(Ⅱ) ions.The mechanism of thermolysis was studied based on TG-DTA-DTG analyses for the complexes and elemental analyese and IR spectra for intermediate of thermolysis. |
