  摘要：

  Treatment of the uranium(IV) complexes [{ML1(py)}(2)U-IV] (M = CU, Zn; L-1 = N, N'-bis(3-hydroxysalicylidene)-1,3-propanediamine) with silver nitrate in pyridine led to the formation of the corresponding cationic uranium(V) species which were found to be thermally unstable and were converted back into the parent U-IV complexes; no electron transfer was observed in solution between the U-IV and U-V compounds. In the crystals of [{ML1(py)}(2),U-IV][{ML1(py)}(2)U-V][NO3], the neutral U-IV and cationic U-V species are clearly identified by the distinct U-O distances. Similar reaction of [{ZnL2(py)}(2)U-IV] [L-2 = N,N'-bis(3-hydroxysalicylidene)-1,4-butanediamine] with AgNO3 gave crystals of [{ZnL2(py)}U-V{ZnL2(py)(2)}][NO3] but the copper counterpart was not isolated. Crystals of [{ZnL1(py)}(2)U-V][OTf] (.) THF (OTf = OSO2CF3) were obtained fortuitously from the reaction of [Zn(H2L1)] and U(OTf)(3).(c) 2006 Elsevier Ltd. All rights reserved.
