Hydrothermal synthesis and crystal structure of organic-inorganic hybrid vanadate: [Zn(phen)(H2O)V2O6] (phen=1,10-phenanthroline)

摘要

A new organic-inorganic hybrid vanadate with the formula [Zn(phen)(H2O)V2O6] (1) has been synthesized under hydrothermal conditions. 1 crystallizes in the monoclinic space group P-1 with a = 7.883(3) Angstrom, b = 9.389(3) Angstrom, c = 10.9212(13) Angstrom, a = 89.26(2)degrees, beta = 69.76(2)degrees, gamma = 76.40(3)degrees, V = 735.1(4) Angstrom(3) and Z = 2. Single-crystal X-ray crystallography shows that 1 exhibits ribbon-like structure covalently constructed from cyclic tetramer [V4O12](4+) subunits and [Zn(phen)(H2O)](2+) fragments. Other characterizations by elemental analysis, IR and thermal analysis are also described in this paper. (C) 2004 Elsevier B.V. All rights reserved.
