Preparation of some phosphidoindium compounds, and the crystal structures of In(PBut2)3 and [Et2InPBUt2]2

The reaction of LiPBut 2 with InI3 yields the monomeric compound In(PBut 2)3, while the action of But 2PH on InEt3 affords the dimeric phosphide [Et2InPBut 2]2. Both compounds have been fully characterised by analytical, spectroscopic, and X-ray diffraction methods.
