摘要：

A single crystal X-ray diffraction study of (NH4)(2)[(UO2)C2O4(CH3COO)(2)] was performed. The compound crystallizes in the monoclinic system; unit cell parameters (at 100 +/- 2 K): a = 6.793(2), b = 18.866(6), c = 20.730(7) angstrom, beta = 90.040(7)degrees, space group P2(1)/c, Z = 8, V = 2656.5(14) angstrom(3), R = 0.0495. The main structural units of the crystals are mononuclear complexes [(UO2)C2O4(CH3COO)(2)](2-) belonging to crystal-chemical group AB(3)(01) (A = UO22+, B-01 = CH3COO- and C2O42-) of uranyl complexes. The uranium-containing anions are linked with ammonium cations by electrostatic interactions and a system of hydrogen bonds. The results of the X-ray diffraction analysis of the compound are well consistent with the IR data.
