Abstract

Two series of polynuclear coordination compounds [AlLn(C6O7H11)2(C6O7H10)2]·4H2O (where Ln(III) = La, Nd, Er; C6O7H11 - = gluconate anion) and [AlLn(CH2(NH2)COOH)4](NO3)6·4H2O (where Ln(III) = Nd, Er; CH2(NH2)COOH = glycine) have been synthesized by two soft chemical methods: complexation method and self-propagating combustion method. These compounds have been characterized by elemental chemical analysis and physico-chemical measurements (IR and UV-Vis spectra). The mixed oxides obtained by the decomposition of these compounds have been characterized by X-ray diffraction, SEM, IR and UV-Vis spectra..
