EXAMPLE - - Indium (In)(selenium(Se)-sec-butyl(Bu))3 (0.64 g), silver(Ag)Se-sec-Bu (0.15 g) and copper(Cu)Se-sec-Bu (0.12 g) were charged into an inert atmosphere glovebox. Benzene (15 ml) was added, and the reaction mixture was stirred at 25 degrees C for 30 minutes. An orange solution was obtained, which was filtered through a filter cannula and the mother liquor was collected. The solvent was then removed under dynamic vacuum to obtain (Cu(0.5)Ag(0.5)(Se-sec-Bu)4In) (0.88 g, 97%).
