SYNTHESIS AND CHARACTERIZATION OF NOVEL BINUCLEAR CHROMIUM(III) COMPLEXES BRIDGED BY AROMATIC HETEROCYCLIC-COMPOUNDS

Two novel types of binuclear bis(acetylacetonato)chromium(iii) complex es bridged by imidazole-4,5-dicarboxylate, 1,2,3-triazole-4,5-dicarbox ylate and pyrazole-3,5-dicarboxylate and a binuclear complex bridged b y both pyrazolate and hydroxide ligands were prepared and characterize d by elemental analysis and positive-ion fast atom bombardment mass sp ectrometry. Their spectroscopic and magnetic properties were examined by means of luminescence, H-2 NMR and magnetic susceptibility measurem ents.
