Novel Bimetallic Thiocarboxylate Compounds as Single-Source Precursors to Binary and Ternary Metal Sulfide Materials

The binuclear compounds [(Ph 3 P)CuM(SC{O}Ph) 4 ] (M = Ga ( 1 ) or In ( 2 )), [(Ph 3 P) 2 AgGa(SC{O}Ph) 4 ] ( 3 ), [(Ph 3 P) 2 AgIn(SC{O}R) 4 ] (R = Me ( 4 ) or Ph ( 5 )) have been synthesized and characterized. The solid-state structures of compounds 1 − 3 have been determined by X-ray crystallography. Thermogravimetry and pyrolysis studies revealed that these compounds decompose to give the corresponding ternary metal sulfide materials. However, using the aerosol-assisted chemical vapor deposition (AACVD) method, In 2 S 3 thin films were obtained from 2 and AgIn 5 S 8 thin films were obtained from compounds 4 and 5 .
