SYNTHESIS AND CRYSTAL-STRUCTURE OF [(N-C4 H9)(4)N](2)[(OC14H8O)(2)MO4O10(OCH3)(2)]

To study the catalysis of polymolybdate, the title complex was synthes ized by phenanthraquinone as the substrate. The molecular structure of the complex was determined by X-ray diffraction method. The crystal i s monoclinic with space group P2(1)/c, a = 1.314 9 (5) nm, b = 1.866 6 (8) nm, c = 1.890 3(3) nm, beta = 104.06(3)degrees, V = 3.310 (4) nm(3 ), Z = 2, D-c = 1.521 g/cm(3). Independent reflections of 3 505 were c ollected, in which 1 382 were observed. The final R = 0.078 and R(w) = 0.078. The result of structure analysis indicate that the complexes w ith different structures can he formed by phenanthraquinone as the lig and with the same polymolybdate under different experimental condition s.
