摘要：

Two novel vanadium selenites {[VO(OH)(H2O)](SeO3)}(4)(.)2H(2)O 1 and (H3NCH2CH2NH3)[(VO(SeO3)(2)] 2 were synthesized by hydrother-mal method and their crystal structures were determined by single-crystal X-ray diffraction. It is characterized by inductively coupled plasma (ICP), thermogravimetric (TG) and elemental analyses. Compound 1 crystallizes in the monoclinic system, space group C2/c, a = 21.2250(11) Angstrom, b = 12.6309(6) Angstrom, c = 17.0249(10) Angstrom, beta = 96.830(3)degrees, V = 4531.8(4) Angstrom(3) and Z = 8, R-1 [I > 2sigma(I)] = 0.0344, wR(2) [I > 2sigma-(I)]=0.119; Compound 2 crystallizes in the monoclinic system, space group P2(1)/c, a = 9.6389(4) Angstrom, b = 6.9922(3) Angstrom, c = 15.0324(5) Angstrom, beta = 102.297(2)degrees, V = 989.90(7) Angstrom(3) and Z = 4(1) R-1 [I > 2sigma(I)] = 0.0452, wR(2) [I > 2sigma(I)] = 0.117. {[VO(OH)(H2O)](SeO3)}(4)(.)2H(2)O has a 1D structure constructed from the {[VO(OH)(H2O)]SeO3)}(infinity) chains. (H3NCH2CH2NH3)[(VO)(SeO3)(2)] has a layered structure composed of alternating VO5 and SeO3 units with protonated ethylenediamine as interlayer guest. (C) 2003 Elsevier Science (USA).
