Rezumat

Heterometallic complexes of chromium (III) with some 3d metals have been synthesized based on nitrilotriacetic acid (H3 nta), like M(bpy)2 Cr2 (OH)2 (nta)2·nH2O, where M = Mn 2 , Co2 , Ni 2 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.
