the metal centre and redistribution of the ligands, giving [UCp3(dmpz)] (8), pyrazabole (9) and [U(TpMe2)(dmpz)3] (10). The complexes have been fully characterized by spectroscopic methods and the structures of 1, 2, and 5 were confirmed by X-ray crystallographic studies. In the solid state the complexes exhibit distorted pentagonal bipyramidal geometries.
                                    [U(Tp ME2)2(NR 2)](R = Ph,SiMe 3)与质子底物如2,4,6-三甲基
苯酚(HOC 6 H 2 -2,4,6 -Me 3)的反应, 
3,5-二甲基吡唑(Hdmpz),
2-巯基吡啶(HSC 5 H 4 N)和
苯乙炔(HCCPh)得到相应的[U(Tp ME2)2(OAr)](Ar = C 6 H 2 -2,4, 6-ME 3)(1),[U(TP ME2)2(dmpz)](2),[U(TP ME2)2(η 2-SC 5 H 4 N)](3)和[U(Tp ME2)2(CCPh)](4)化合物。[U(Tp ME2)2(NR 2)]与Me 3 SnCl或Me 3 SiBr的反应分别得到[U(Tp ME2)2 Cl](5)和[U(Tp ME2)2 Br](6) ,产量高。酰
氨基的前体未能与
环戊二烯反应,但复分解[U(TP ME2)2 I]与
NACP,得到[U(κ 3 -TP ME2)(κ
