摘要：
Single crystals of Ba-2[(UO2)(C2O4)(2)(NCS)]NCS center dot 7H(2)O were prepared and studied by X-ray diffraction. The crystals are monoclinic, space group P2(1)/c, Z= 4, a = 13.508(5) angstrom, b = 12.268(4) angstrom, c = 14.965(5) angstrom, beta = 115.38(1)degrees, V = 2240.6(13) angstrom(3). The main structural units in the crystal are the island complex species [(UO2)(C2O4)(2)(NCS)](3-) corresponding to the crystal chemical group AB(2)(01) M-1 (A = UO22+, B-01 = C2O42-, M-1 = NCS-) of uranyl complexes, which are united into a three-dimensional framework through electrostatic interactions and through hydrogen bonds involving oxalate and isocyanate ions and water molecules.
