Popis:	Compounds (CN3H6)2[UO2(OH)2(NCS)]NO3 (I) and β-Cs3[UO2(NCS)5] (II) are synthesized and studied by IR spectroscopy and single-crystal X-ray diffraction. I and II crystallize in the orthorhombic system. For I, a = 12.2015(13) A, b = 7.3295(8) A, c = 16.310(2) A, space group Pnma, Z = 4, and R = 0.0327; for II, a = 21.7891(6) A, b = 13.5120(3) A, c = 6.8522(2) A, space group Pnma, Z = 4, and R = 0.0268. In structure I, complex groups form infinite chains [UO2(OH)2(NCS)] − belonging to the AM 2 2 M 1 crystal chemical group of uranyl complexes (A = UO 2 2+ , M 2 = OH−, and M 1 = NCS−). The main structural elements of crystals II are mononuclear [UO2(NCS)5]3− groups belonging to the AM 5 1 group of uranyl complexes (A = UO 2 2+ and M 1 = NCS−). In I and II, uranium-containing complexes are connected with outer-sphere cations by electrostatic interactions, and in I a system of hydrogen bonds also contributes to their binding. Specific features of the packing of complex [UO2(NCS)5]3− groups in the structures of two modifications of Cs3[UO2(NCS)5] are discussed.
