Reactions of triorganoindium etherate with protic ligands in benzene at room temperature have afforded diorganoindium complexes of the type, [R2I_n(L)]n [R = Me, Et; L = (C₅H₄N)CH₂O; (C₅H₄N)CH₂CHO; 2-MeOC₆H₄O; C₆H₅CO₂; 2-MeOC₆H₄CO₂; 2-(C₅H₄N)CO₂; 2-(C₉H₆N)CO₂; 2-(C₄H₃O)-CO₂]. These complexes have been characterized by indium analysis, IR, NMR (¹H. ¹³C{lH}) and mass spectral data. The mass spectra reveal that these complexes are associated in the solid state. The complex Et₂In(O₂C-C₉H₆N) shows photoluminescence on excitation with 370 nm radiation.
