SYNTHESIS, STRUCTURE AND SPECTRA PROPERTIES OF THE NEODYMIUM MOLYBDOGERMANATE HETEROPOLY COMPLEX

K7H6[Nd(GeMo11O39)2].18H2O was first synthesized and the crystal structure was determined. Crystal structure data are as follows: monolinic, space group P2(1)/n, a = 1.7095(4), b = 2.6895(3), c = 2.1214(5) nm, beta = 103.11 (2)-degrees, V = 9.4994(3) nm3, Z = 4, D(m) = 3.14g/cm3, D(c) = 3.05g/cm3, mu(MoK-alpha) = 43.7 cm-1. Experimental evidence and theoretical foundation of the method inferring the molecule structure of heteropoly compounds using their IR spectra were gaved by studying IR spectra properties of the complex with results of structural analysis. Electronic spectra prove that 4f-obital of Nd3+ take part in bonding in the complex.
