摘要：
Two new hybrid vanadium arsenates (2,2'-bpy)(2)((VO2)-O-V)(2)(ASO(4)).H3O.H2O 1 and (2,2'-bPY)(2)V4O7(HA(s)O(4))(2) 2 (2,2'-bpy = 2,2'-bpyridine) were synthesized under hydrothermal reaction conditions and structurally characterized by single-crystal X-ray diffraction, thermogravimetric analysis (TGA), IR, powder XRD and elemental analyses. Crystal data for 1: monoclinic, C2/c, a = 13.867(7) Angstrom, b = 22.351(10) Angstrom, c = 9.252(4) Angstrom, beta = 103.857(4)degrees, V = 2784(2) Angstrom(3), Z = 4. Crystal data for 2: triclinic, P-1, a = 8.4401 (1) Angstrom, b = 9.3309(11) Angstrom, c = 9.6996(10) Angstrom, alpha = 96.910(4)degrees, beta = 110.860(2)degrees, gamma = 98.595(4)degrees, V = 693.23(11) Angstrom(3), Z = 1. Compound 1 is composed of discrete {(VO2)(2)(AsO4)} 3-membered rings bonded to two 2,2-bpy ligands. Compound 2 exhibits a 2D arsenic vanadate network decorated with 2,2'-bpy ligands.
