摘要: Zinc and cadmium complexes of 1,1,5,5-tetraalkyl-2-4-dithiobiurets [M(N(SCNR2)2)2] [M = Zn, R methy (1), ethyl (2) M Cd, methyl (4), (5)] 1,1,5,5-tetraalkyl-2-thiobiurets [M(SON(CNR2)2)2] isopropyl (3) (6)] have been synthesized. The single crystal X-ray structures (2), (3), (5) were determined. Thermogravimetric analysis confirmed that all six decomposed in a step to their corresponding metal sulfides. used as source precursors for the deposition zinc sulfide (ZnS), (CdS), (ZnxCd1−xS) thin films by aerosol assisted chemical vapor (AACVD). (1) deposited cubic ZnS with small rods granular crystallites at 300 350 °C, whereas 400 450 °C hexagonal dominant. Complex gave temperatures. Cadmium complex...
