Complex of uranyl citraconate with dimethylacetamide: Synthesis and structure

Abstract

The complex [UO2(C5H4O4)(Dmа)] (I), where C5H4O42– is citraconate ion and Dmа is dimethylacetamide, was synthesized and studied by single crystal X-ray diffraction analysis. The complex has layered structure and belongs to crystal-chemical group AQ21M1 (A = UO22+, Q21 = C5H4O42–, M1 = Dmа) of uranyl complexes. Structural features of all the known uranyl complexes with citraconate anions are considered. Nonvalent interactions in the crystal structure of I are characterized using the method of molecular Voronoi–Dirichlet polyhedra. The IR spectrum of I is analyzed.
