Treatment of UO2X2 (X = OAc, Cl, NO3) with 1 mol equiv of (py)2CO in THF afforded the adducts [UO2X2(py)2CO}] in almost quantitative yields. The same reactions in MeOH, in the presence of NEt3 for X = Cl and NO3, gave yellow crystals of [(UO2X)2μ-(py)2C(OMe)O}2]·MeOH (X = OAc, 1·MeOH and X = Cl, 2·MeOH) and [UO2(NO3)}2μ-(py)2C(OMe)O}2] (3). Reactions of UO2X2 (X = OAc, Cl) with 2 mol equiv of (py)2CO
用在THF中的1摩尔当量的(py)2 CO处理UO 2 X 2(X = OAc,Cl,NO 3)以几乎定量的产率得到加合物[UO 2 X 2 (py)2 CO}]。在NEt 3下,对于X = Cl和NO 3,在MeOH中进行相同的反应,得到黄色晶体[(UO 2 X)2 μ-(py)2 C(OMe)O} 2 ]·MeOH(X = OAc,1 ·MeOH,X = Cl,2 ·MeOH)和[UO 2(NO 3)} 2 μ-(py)2 C(OMe)O} 2](3)。UO 2 X 2(X = OAc,Cl)与2摩尔当量的(py)2 CO和NEt 3在MeOH中的反应或将1和2用1摩尔当量的(py)2 CO和NEt 3进一步处理得到
