Synthesis and physico-chemical studies of heterometallic nitrilotriacetates of chromium(III) with some 3d metals [Articol]
(Academia de Știinițe a Moldovei, 2006) Ciornea, Victor; Gulea, Aurelian
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+; bp = 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.
