【 摘 要 】

Heterometallic complexes of chromium (III) with some 3d metals have been synthesized based on nitrilotriacetic acid (H3nta), like M(bpy)2Cr2(OH)2(nta)2·nH2O, where M = Mn2+, Co2+, Ni2+ and Zn2+; bpy = α,α′- bipyridine; n = 8 or 9. Their chemical composition has been determined from the results of the elemental analysis and thermogravimetric study. The coordination modes of the nta3 ̄ ligand and the type of chemical bonds have been proposed basing on IR spectra.
