The synthesis of homoleptic and heteroleptic alkylindium derivatives (generally as diethyl ether adducts) was carried out in high yields from InI₃. The nuclear magnetic resonance and mass spectra of the compounds Me_nInEt_3n (n = 0, 1, 2, or 3) and of their trideuteromethyl analogues showed that both heteroleptic Me₂InEt and MeInEt₂ exist as single compounds, although disproportionation to InMe₃ and InEt₃ has been observed at temperatures slightly higher than room temperature. The crystal structure of unusual diphosphine-bridged adduct, [(InMe₃)diphos(Me₂InEt)] · [(InMe₃)diphos(InMe₃)], (diphos = (C₆H₅)₂PCH₂CH₂P(C₆H₅)₂ is reported.
