Abstract

An X-ray diffraction study of the single crystals of (C2H7N4O)2[(UO2)2(OH)2(C2O4)(CHO2)2] was carried out. The compound crystallizes in the triclinic system, space group \(P\bar 1\), Z = 2, a = 5.5621(8) Å, b = 8.1489(10) Å, c = 11.8757(16) Å, α = 88.866(7)°, β = 82.204(6)°, γ = 87.378(6)°, V = 532.7(1) Å3, ρcalcd = 2.988 g/cm3. The main structural units in the crystal are the [(UO2)2(OH)2(C2O4)(CHO2)2)]2− chains corresponding to the crystal chemical group A2M 22 K02M 12 (A = UO 2+2 , M2 = OH−, K02 = C2O 2−4 , M1 = CHO −2 ) of uranyl complexes. The chains are united into a three-dimensional framework through the electrostatic interaction and hydrogen bonds involving uranyl, oxalate, and hydroxyl groups, formate ions, and 1-carbamoylguanidinium cations.
