摘要
A novel compound, [HN(C2H4)(3)N][(VO)(2)(HPO3)(2)(OH)(H2O)] (.) H2O, was hydrothermally synthesized and characterized by single crystal X-ray diffraction. This compound crystallizes in the monoclinic system with the space group C2/c and cell parameters a = 11.0753(3) Angstrom, b = 17.8265(6) Angstrom, c = 16.5229(5) Angstrom, and beta = 92.362(2)degrees. The structure of the compound consists of vanadium phosphite layers which are built up from the infinite one-dimensional chains of [(VO)(H2O)(HPO3)(2)](2-) of octahedral VO5(H2O) and pseudo pyramidal [HPO3], and bridging binuclear fragments of [VO(OH)](2). Thermogravimetric analysis and magnetic susceptibility data for this compound are given. (C) 2003 Elsevier Science (USA). All rights reserved.
