Abstract
The uranyl complexes with malonic acid dianions [UO2(C3H2O4)(CO(NH2)2)]·H2O (1), [UO2(C3H2O4)(CONH2NMe2)]·H2O (2), and [UO2(C3H2O4)(MeCONMe2)] (3) were synthesized and characterized by X-ray crystallography. The structural units [UO2(C3H2O4)L] in the crystals of 1–3 refer to the AK21M1 crystal chemical group (A = UO2 2+, K21 = C3H2O4 2−, M1 = L) of uranyl complexes; the crystals of 1 have a framework structure and 2 and 3 have a chain structure. Some structural features of the [UO2(C3H2O4)L] complex groups are discussed.
