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

The triphosphine-indane TPI([o-i-Pr2P(C6H4)](3)In) has been prepared and found to react with [Pd(P-t-Bu-3)(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.
