Compound (CN{sub 3}H{sub 6}){sub 2}[(UO{sub 2}){sub 2}(C{sub 2}O{sub 4})(CH{sub 3}COO){sub 4}] is synthesized and characterized by IR spectroscopy and single-crystal X-ray diffraction [a = 8.5264(2) A, b = 13.8438(4) A, c = 10.7284(2) A, {beta} = 103.543(1) Degree-Sign , space group P2{sub 1}/n, Z = 2, and R = 0.0258]. The main structural units of the crystals are binuclear [(UO{sub 2}){sub 2}C{sub 2}O{sub 4}(CH{sub 3}COO){sub 4}]{sup 2-} groups, which belong to the A{sub 2}K{sup 02}B{sub 4}{sup 01} crystal chemical group of uranyl complexes (A = UO{sub 2}{sup 2+}, K{sup 02} = C{sub 2}O{sub 4}{sup 2-}, and B{sup 01} = CH{sub 3}COO{sup -}). The coordination polyhedron of the uranium atom is the UO{sub 8} hexagonal bipyramid with the oxygen atoms of the uranyl ion at the axial positions. Uranium-containing groups and guanidinium cations are connected by electrostatic interactions and by the hydrogen bond system, which involves hydrogen atoms of guanidinium cations and oxygen atoms of oxalate and acetate anions. The results of the spectroscopic study of the compound agree with the X-ray diffraction data.
