摘要：

Polyoxoanions of tungsten, molybdenum, and vanadium have been the subject of interest since their wide variety of compositions, structures, and properties give rise to numerous important applications[1]. From the NH4VO3/Na2Sx (or (NH4)2Sx) reaction system we synthesized several spherical octadecavanadates with Na+,K+, NH4+ or I encapsulated using hydrothermal method. These complexes include (NH4)11[V18O42(Na)]·(H2O)20 1; (NH4)11[V18O42(K)]·(H2O)6, 2; (NH4)10(Na)[V18O42(Na)]·(H2O)26, 3; (NH4)11[V18O42(NH4]·(H2O)20, 4; and (NH4)20(I)7[V18O42(I)]·(H2O)12, 5, in which the structures of 1, 2, 3, and 5 have been determined by X-ray analyses. In the analogous reaction system of (NH4)2MoS4/(NH4)2Sx, we also obtained one ellipsoidal octadecamolybdate, (NH4)4[Mo18O54(2SO4)]·(H2O)4, 6 with a standard Wells-Dawson structure[2]. The Ortep drawings of the two kinds of structures are viewed as follows.
