in the phosphine. The co-ordination chemistry of these ligands has been investigated via the synthesis of examples of late transition-metal complexes. The results of single crystal structural determinations of cis-[PtCl2PPh2(CFCF2)}2] and [AuCl[PPh2(CFCF2)]}2]·0.5CH2Cl2 are reported. In both of these molecules short metal–phosphorus distances [d(Pt–P)av = 2.231(3) and d(Au–P)av = 2.217(2) Å] are
衍生自CF 3 CH 2 F的全氟乙烯基锂与氯取代的膦反应生成 高产率的PPh m(CF CF 2)n和P(CF CF 2)n Cl m(n + m = 3)类型的全氟乙烯基膦。空气和水分稳定化合物PPh(CF = CF 2)2的低温晶体结构测定提供了第一个报告的含全氟乙烯基材料的结构数据。在膦的全氟乙烯基中,CF键的距离[1.310(4),1.321(4),1.353(3)Å]有相当大的变化。这些配体的配位化学已经通过合成后期过渡金属配合物的实例进行了研究。顺式-[PtCl 2 PPh 2(CF CF 2)} 2 ]和[AuCl [PPh 2(CF CF 2)]} 2 ]·0.5CH 2 Cl 2的单晶结构测定结果被报道。 与相似的膦配合物的典型距离相比,在这两个分子中都观察到了较短的金属-磷距离[ d(Pt–P)av = 2.231(3)和d(Au–P)av = 2.217(2)Å]。在对配合物[Mo(CO)5
