Synthesis and characterisation of titanium pyridine- and pyrimidine-thiolates and their application as precursors to titanium disulfide
摘要:
The reaction of TiCl(4) with pyridine- and pyrimidine-thiol has been investigated. Reaction of TiCl(4) with 3 equiv. of 2-mercaptopyridine and 3 equiv. of tert-butylpyridine in toluene at room temperature resulted in the formation of the tris(pyridine-2-thiolate) complex [TiCl(SC(5)H(4)N)(3)] (1). The related reaction between TiCl(4) with 3 equiv. of 2-mercaptopyrimidine and 3 equiv. of tert-butylpyridine in toluene at room temperature resulted in the isolation of the complex [TiCl(SC(4)H(3)N(2))(3)] (2). Compound 2 has been characterised by X-ray crystallography. Low pressure CVD of 1 and 2 produced brown/gold films of TiS(2)/TiO(2) on glass substrates at 550 and 600 degrees C. (c) 2006 Elsevier Ltd.
