摘要：

Single crystals of the compounds (C3N6 H-7)(4)(CN3H6)(2)[UO2(CrO4)(4)] center dot 4H(2)O (I) and (H3O)(6)[UO2(CrO4)(4)] (II) are synthesized, and their structures are investigated using X-ray diffraction. Compound I crystallizes in the triclinic system with the unit cell parameters a = 6.3951(8) angstrom, b = 10.8187(16) angstrom, c = 16.9709(18) angstrom, alpha = 93.674(4)degrees, beta = 97.127(4)degrees, gamma = 92.020(4)degrees, space group, P (1) over bar Z = 1, V = 1161.6(3) angstrom(3), and R = 0.0470. Crystals of compound II belong to the monoclinic system with the unit cell parameters a = 14.3158(4) angstrom, b = 11.7477(3) angstrom, c = 13.1351(4) angstrom, beta= 105.836(1)degrees, space group C2/c, Z = 4, V = 2125.2(1) angstrom(3), and R = 0.0213. The uranium-containing structural units of crystals I and II are mononuclear anionic complexes of the composition [UO2(CrO4)(4)](6-) with an island structure, which belong to the crystal-chemical group Am-4(1) (A = UO22+, M (1) = CrO42-) of the uranyl complexes. The [UO2(CrO4)(4)](6-) anionic complexes are joined into a three-dimensional framework through the electrostatic interactions with outer-sphere cations and a system of hydrogen bonds.
