摘要：
Synthesis, IR spectral study, and X-ray diffraction analysis of crystals of UO2(C4H4O4) center dot C3H6N2O] (I) and [UO2(C4H4O4) center dot C4H9NO] (II) were performed. Both compounds are crystallized in monoclinic syngony with unit cell parameters: a = 7.7582(1) , b = 10.1601(2) , c = 14.6234(3) , beta = 103.753(1)A degrees, space group P2(1)/c, Z = 4, R = 0.0219 (I); a = 8.2894(4) , b = 12.3667(5) , c = 12.0728(4) , beta = 96.464(2)A degrees, space group P2(1)/n, Z = 4, R = 0.0330 (II). Complexes [UO2(C4H4O4)L] (L = C3H6N2O or C4H9NO) in the crystals of I and II are related to crystal-chemical group A(K-21-4)M-1 (A = UO (2) (2+) , K-21-4 = C4H4O (4) (2-) , M-1 = L) of uranyl complexes and have layered structure. The effect of succinate ion conformation on the topology of all known complexes [UO2(C4H4O4)L] is discussed.
