Synthesis, strcuture and spectra properties of the neodymium molybdogermanate heteropoly complex

K7H6Nd(GeMo11O39)2].27H2O was synthesized, and the crystal structure was determine Crystal data: monoclinic, space group P21/n, a 1.7095(4), b 2.6895(3), c 2.1214(5) nm, b = 103.11(2)? Z = 4, R = 0.090. Experimental evidence and theor. foundation of the method inferring the mol. structure of heteropoly compounds using their IR spectra were given by studing IR spectral properties in comparison with results of the structural anal. Electronic spectra prove that a 4f orbital of Nd3+ takes part in bonding in the complex.
