Thermal deposition of TiS films from volatile Ti(SBut)4

Syntheses, Structures, and Properties of Trinuclear Copper(I)/Titanium(IV) Thiolate Complexes

“…In this respect, it is interesting to note that titanium sulfide films produced by CVD processes with substrate temperatures below 800°C are usually found to be amorphous. [3,[6][7][8] In addition, we found that the positions of the broad peaks (marked by an asterix) are similar to those reported for some LiTiO 2 phases. [45,46] However, this would require reduction of Ti 4+ to Ti 3+ and the presence of distinct amounts of moisture and the presence of oxygen should also lead to the formation of PhSSPh which was not found in the cleavage products.…”

“…The formation of SR 2 and metal sulfides is a well established decomposition pathway for transition metal thiolates M(SR) 2 of group 12 (M = Zn, Cd), [43] whereas for binary titanium thiolato complexes different reaction products have been observed. For Ti(StBu) 4 either the formation StBu 2 and tBuSStBu [3] 9 ] resulted in the volatile decomposition products Et 2 NH and PhCH 2 SSCH 2 Ph. [7] Complex 2 visibly starts to decompose at around 150°C with the formation of a dark powder and a colorless oil, which condenses outside the oven.…”

“…[3] Thiol adducts of the type [TiC1 4 (HSR) 2 ] (R = c-C 6 H 11 or c-C 5 H 9 ) were found to afford bronze colored films of polycrystalline TiS 2 in CVD experiments (200-600°C, at 0.1 Torr). [4,5] [8] which led to the formation of films of TiS 2 .…”

“…[1] Interest in titanium thiolate compounds arises from the fact that such compounds can serve as single-source precursors for the formation of thin films of titanium sulfides by chemical vapor deposition (CVD). [2,[3][4][5][6][7][8] Titanium disulfide is also of interest since Whittingham first demonstrated fast, reversible Li insertion into TiS 2 over the solid solution range 0 Յ x Յ 1 of Li x TiS 2 . [9,10] However, only a few homoleptic titanium complexes with monodentate thiolato ligands have been characterized by single-crystal X-ray to date.…”

Syntheses, Structures and Theoretical Investigations of [Li(thf)4]2[Ti2Cu8S4(SPh)10] and [Ti2Ag6S6Cl2(PPhiPr2)6]

“…For example, TiS films were obtained by gas-phase decomposition of Ti(StBu) 4 under relatively mild conditions. [1] The first well-characterized titanium thiolate was reported in 1987 with bulky aryl substituents, [Li(OEt 2 ) 3 ][Ti(S-2,4,6-iPr 3 C 6 H 2 ) 4 ]. [2] Several other known examples like [Li(C 4 H 8 O) 4 ][Ti 2 (SPh) 9 ], [3] [NMe 2 H 2 ][Ti 2 -(SMe) 9 ] and [Ti 3 (SMe) 12 ] have been isolated only in low yields.…”
