摘要

Crystals of [(UO~(2))~(2)(mal)(Cl)~(2)(DMA)~(4)] (mal_(2–)is malonate ion and DMA is dimethylacetamide) have been synthesized and studied by X-ray crystallography. The key structure units are binuclear island complexes [(UO~(2))~(2)(mal)(Cl)~(2)(DMA)~(4)], which belong to the A ~(2) Q _(02) M ~(6)_(1) crystal-chemical group ( A = UO ~(2)_(2+) , Q _(02)= mal_(2–), M _(1)= Cl_(–)and DMA) of uranyl complexes. The complexes form a framework through a system of intermolecular nonbonded interactions, which are characterized by means of the Voronoi–Direchlet molecular polyhedron method.
