Abstract:
An x-ray structural investigation of single crystals of [(C2Hs)2NH2]4 NH4 H[V(V3Mo9)040], which were obtained from sodium molybdovanadate solutions, has been carried out (Syntex P21 autodiffractometer, Mo Kalfa radiation, 3151 values of F(khs), R = 0.064, R w= 0, 058) The crystals are monoclinic, a = 13.217(2), b = 20.279(4), c=21.440(6) A, beta = 98,8 (2), V = 5679(3) A3, dcal = 2.38 g/cm 3, Z = 4. The characteristic fragment in the structure is a Keggin-type heteropoly anion with metal atoms (3V + 9Mo) statistically located at 12 positions within deformed octahedrons
and with a tetrahedrally coordinated central V atom. The bonding between the heteropoly anions is realized by means of contacts with diethylamine molecules, NH4 ammonium groups, and an acidic proton. The 51V NMR spectra have been investigated, and they confirmed the composition and structure of the complex [V4MogO40] 6- and
showed that it is mainly dissociated into mixed isopoly anions of the 6 series and an Mo-subsituted decavanadate in a DMFA solution.
