Original Transition Metal→Indium Interactions upon Coordination of a Triphosphine−Indane

The triphosphine−indane TPI ([o-i-Pr2P(C6H4)]3In) has been prepared and found to react with [Pd(P-t-Bu3)2] and [AuCl(SMe2)]. According to X-ray diffraction analyses and DFT calculations, the ensuing complexes both display original donor−acceptor M→In interactions, although of markedly different nature and magnitude.

三膦茚TPI（triphosphine−indane TPI，化学式为[o-i-Pr₂P(C₆H₄)]₃In）已被成功合成，并被发现可与[Pd(P-三叔丁基膦)₂]和[AuCl(SMe₂)]发生反应。通过X射线衍射分析与密度泛函理论（DFT，Density Functional Theory）计算可知，所得到的两种配合物均展现出新颖的供体-受体型M→In相互作用，尽管二者的作用本质与强度存在显著差异。
