| Abstract: | The complex [UO2(OH)(CO(NH2)2)3]2(ClO4)2 (I) was synthesized. A single crystal X-ray diffraction study showed that compound I crystallizes in the triclinic system with the unit cell parameters a = 7.1410(2), b = 10.1097(2), c = 11.0240(4) Å, α = 104.648(1)°, β = 103.088(1)°, γ = 108.549(1)°, space group (Pbar 1), Z = 1, R = 0.0193. The uranium-containing structural units of the crystals are binuclear groups [UO2(OH)· (CO(NH2)2)3] 2 2+ belonging to crystal-chemical group AM2M 3 1 [A = UO 2 2+ , M2 = OH?, M1 = CO(NH2)2] of uranyl complexes. The crystal-chemical analysis of nonvalent interactions using the method of molecular Voronoi-Dirichlet polyhedra was performed, and the IR spectra of crystals of I were analyzed. |
