摘要：
Malonate-thiocyanate complex (NH4)3[UO2(C3H2O4)2(NCS)] · 2H2O is synthesized and studied by X-ray diffraction. The compound crystallizes in the monoclinic system: a = 13.9983(4) Å, b = 8.1947(2) Å, c = 16.4678(4) Å, β = 100.846(1)°, space group Cc, Z = 4, and R = 0.0158. The main structural units of the crystal are mononuclear [UO2(C3H2O4)2(NCS)]3− groups belonging to the AB201M1 crystal chemical group of uranyl complexes (A = UO22+, B01 = C3H2O42−, M1 = NCS−). Discrete uranium-containing groups are connected by electrostatic interactions with ammonium ions and by hydrogen bonds. Some specific structural features of crystals containing [UO2(L)2(NCS)]3− complexes, where L is the oxalate or malonate ion, are discussed.
