2 ] 2 . When [UCl 6 ] 2− is employed, only the chlorocomplexes are obtained. The complexes for R = Me, Et, Pr i , OMe, OEt, OPr i , Ph and C 6 H 11 have been characterised by elemental analysis, IR and NMR spectroscopy. From one reaction of UVl 4 and NaS 2 PMe 2 , the complex UO 2 (S 2 PMe 2 ) 2 · Me 3 PO was obtained by an unknown route. The crystal structures have been determined for two alcohol adducts
摘要二硫代次膦酸盐R 2 PS 2 H与UO 2 Cl 2在醇R'OH溶液中反应,生成配合物UO 2(S 2 PR 2)2·R'OH。在过量氯离子存在下,将醇置换形成阴离子氯配合物,可以将其分离为[Et 4 N] +盐。在空气中与UCl 4的相似反应在新颖的双氧化反应中产生相同的化合物。最初形成的U(IV)络合物在空气中迅速氧化,生成相应的铀酰化合物,同时,两个配体被氧化,形成二聚体[R 2 PS 2] 2。当使用[UCl 6] 2-时,仅获得氯配合物。R = Me,Et,Pr 1,OMe,OEt,OPr 1,Ph和C 6 H 11的配合物已经通过元素分析,IR和NMR光谱表征。从UVl 4和NaS 2 PMe 2的一个反应中,通过未知途径获得了络合物UO 2(S 2 PMe 2)2·Me 3 PO。已经确定了两种醇加合物,两种氯配合物和氧化膦加合物的晶体结构。UO 2(S 2 PPh 2)2·EtOH:Triclinic,a
