摘要：

The uranyl complexes with malonic acid dianions [UO2(C3H2O4)(CO(NH2)(2))]center dot H2O (1), [UO2(C3H2O4)(CONH2NMe2)]center dot 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 AK(21)M(1) crystal chemical group (A = UO2 (2+), K-21 = C3H2O4 (2-), M-1 = 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.
