Popis: Crystals of [UO2(C5H4O4)(urea)2], where C5H4O4 2– is citraconate ion, were prepared and studied by IR spectroscopy and single crystal X-ray diffraction. The structure of the crystals is formed by chains having the same composition as the compound as a whole and belonging to the crystal-chemical group AТ11M2 1 (A = UO2 2+, Т11 = C5H4O4 2–, M1 = urea) of uranyl complexes. Comparative analysis of nonvalent interactions in the structures of uranyl complexes with citraconate ions was performed by the method of molecular Voronoi–Dirichlet polyhedra.
