analyses, cryoscopic molecular weight measurements and 1H NMR, 31P NMR and IR spectroscopic data. An X-ray structural study was carried out to define the nature of [(Me3SiCH2)2InPPh2]2 in the solid state. The compounds were prepared either by a thermolysis reaction between the group 13 metal trialkyl and PPh2H or by a metathetical reaction between the dialkylmetal halide and KPPh2. Cryoscopic molecular
