Abstract
Uranyl malonate monohydrate [UO2(mal)(H2O)], where mal2– is malonate ion, was synthesized and studied by single crystal X-ray diffraction. The main structural units are electrically neutral [UO2(mal)(H2O)] layers belonging to crystal-chemical group AQ21М1 (A = UO 2+2 , Q21 = mal2–, M1 = H2O) of uranyl complexes. Specific features of the packing of the uranium-containing complexes are discussed on the basis of Voronoi–Dirichlet tessellation. The structural differences between the monohydrate synthesized and the known uranyl malonate trihydrate are considered.
