  The interaction of secondary phosphines with a variety of gold(I) compounds has been studied. In the presence of bases or polar solvents, polymeric gold(I) phosphides [Au(µ-PR2)}n] are formed. When these are obtained in the absence of additional ligands they are soluble, presumably with ring structures. More usually, insoluble forms are found, presumably with chain structures. The probable formation

  已经研究了次膦与各种金（I）化合物的相互作用。在碱或极性溶剂的存在下，形成聚合的金（I）磷化物[Au（µ-PR 2）} n ]。当在没有其他配体的情况下获得它们时，它们是可溶的，大概具有环结构。更通常地，发现不溶形式，大概具有链结构。讨论了由[AuX（PH R 2）]型配合物形成这些物质的可能性，并分离了后者的配合物（X = Cl或Br，R = Ph或对甲苯基）和新型单体磷酸酯桥联阴离子[（AuBr）2（µ-PPh 2）] –描述。在非极性溶剂中，会形成一系列仲膦配合物，[Au（PHPh 2）n ] +（n = 2-4），但是对于n = 3而言，似乎歧化不稳定。该化合物的特征在于31 P nmr和197 AuMössbauer光谱学，[AuBr（PH Ph 2）]情况下的X射线晶体学。
