  Synthesis and crystal structure of [UO2CrO4(C5NH5COO)] · H2O

  摘要：

  Synthesis and X-ray diffraction study of [UO2CrO4(C5NH5COO)] center dot H2O crystals were performed. The compound crystallizes in the monoclinic system with the unit cell parameters a = 7.5025(3) angstrom, b = 11.5188(6) angstrom, c = 13.0518(6) angstrom, beta = 97.877(4), V = 1117.29(9) angstrom(3), space group P2(1)/ n, Z = 4, R = 0.0263. The structure is formed by three [UO2CrO4(C5NH5COO)] layers parallel to (10 (1) over bar). The coordination polyhedron of uranium atoms is a pentagonal bipyramid, whose apices are occupied by oxygen atoms of uranyl, three chromate groups, and two molecules of isonicotinic acid. Crystal chemical formula of the [UO2CrO4(C5NH5COO)] layer can be represented as AT(3)B(2), where A = UO22+, T-3 = CrO42-, and B-2 = C5NH5COO molecules. The isonicotinic acid molecules are in the form of zwitterions.
