Single crystals of the compound {l_brace}NH{sub 2}(C{sub 2}H{sub 5}){sub 2}{r_brace}{sub 2}[(UO{sub 2}){sub 2}C{sub 2}O{sub 4}(CH{sub 3}COO){sub 4}] . 2H{sub 2}O (I) are synthesized, and their structure is investigated using X-ray diffraction. Compound I crystallizes in the monoclinic system with the unit cell parameters a = 9.210(2) A, b = 14.321(3) A, c = 12.659(3) A, {beta} = 105.465(13){sup o}, V = 1609.2(6) A{sup 3}, space group P2{sub 1}/c, Z = 2, and R = 0.0198. The structural units of crystals I are binuclear groups of the composition [(UO{sub 2}){sub 2}C{sub 2}O{sub 4}(CH{sub 3}COO){sub 4}]{sup 2-} with an island structure, which belong to the crystal-chemical group A{sub 2}K{sup 02}B{sub 4}{sup 01} (A = UO{sub 2}{sup 2+}, K{sup 02} = C{sub 2}O{sub 4}{sup 2-}, B{sup 01} = CH{sub 3}COO{sup -}) of the uranyl complexes, diethylammonium cations, and water molecules. The uranium-containing groups are joined into a three-dimensional framework through electrostatic interactions with diethylammonium cations and a system of hydrogen bonds, which are formed with the participation of the atoms involved in the composition of the water molecules, oxalate ions, acetate ions, and diethylammonium cations.
