| Abstract: | rom the reaction between 4,4'-bipyridine and Cu (TTA)2 complex in alcohol, a novel binuclear copper complex, of formula Cu2(TTA)4(4, 4' -- bipy ) ] (TTA:2-thienoyltrifluoro acetate, 4,4'-bipy: 4,4'-bipyridine), has been prepared. The product has been characterized with elemental analysis and infrared spectra. From ESR spectra, the coefficients of molecular orbitals and bond parameters have been obtained. The data of variable-temperature magnetic susceptibility shows that its magnetic property obeys Curie law. Aner discussing the property of 4,4'-bipyridine for propagating magnetic exchange,it is found that as bridging ligand 4,4'-bipyridine is difficult to propagate the magnetic exchange interaction. |
