摘要
The crystal structure of Ba-2(CN3H6)[(UO2)(2)(C2O4)(4)(NCS)(H2O)] . 7H(2)O (I) was studied by X-ray diffraction. The crystals are monoclinic: a = 8.123Angstrom, b = 22.410 Angstrom, c = 18.956 Angstrom, beta = 97.84degrees, Z = 4. The main structural units of crystals of I are mononuclear [UO2(C2O4)(2)(NCS)](3-) and [UO2(C2O4)(2)(H2O)](2-) Complex Species belonging to the AB(2)(01)M(1)(A = UO22+) crystal-chemical group of uranyl complexes, which are combined in a three-dimensional framework by Coulomb interactions with cations and by hydrogen bonds involving water molecules and guanidonium cations.
