“…The S1–Ti–S2 angle is 91.15(4) Å and is similar to the relative titanacycles. [9] The Ti–S bond length averages to 2.389(15) Å, and the S–C bond length averages to 1.856(4) Å. The sum of the bond angles around N1 is 353°, which indicates a degree of planarity, as is typical for N -phenyl derivatives of azadithiolates.…”

A New Route to Azadithiolato Complexes

The reaction of [(MeC5H4)2Ti(SH)2] with cyclic imines with the formula (CH2NR)3 gives 2-aza-1,3-dithiolato chelate complexes [(MeC5H4)2Ti{(SCH2)2NR}] (1, R = Ph; 2, R = Me; 3, R = CH2Ph). These compounds demonstrate that azadithiolate ligands can exist on mononuclear metal centers. The complexes were characterized by 1H NMR spectroscopy, ESI-mass spectrometry, and X-ray crystallography. Variable-temperature 1H NMR studies reveal that the dithiolate ligands undergo ring inversion like other dithiatitanacyclohexanes. Treatment of [(MeC5H4)2Ti{(SCH2)2NPh}] (1) with [Fe(benzylideneacetone)(CO)3] afforded [Fe2{(SCH2)2NPh}(CO)6] in good yield.

The bimetallic complexes fc(µ 2 -S) 2 TiCp 2 (1, fc ) 1,1′-ferrocenyl, Cp ) cyclopentadienyl) and fc(µ 2 -S 2 )(µ 2 -S)TiCp 2 (2) were synthesized by reaction of fc(SH) 2 with Cp 2 TiCl 2 , and from fcS 3 and Cp 2 Ti(CO) 2 , respectively. The novel tetrasulfane fcS 4 was obtained from 2 and SCl 2 . 1,3-Dithia[3]ferrocenophane fcS 2 CH 2 was obtained from fc(SH) 2 and CH 2 Cl 2 in the presence of Cp 2 TiCl 2 and KOH. The molecular and crystal structure of fcS 2 CH 2 was determined by X-ray crystallography; the molecular symmetry is C s . Electrochemical studies on the recently prepared ferrocenophanes fcS 2 -1-SO, fcS 2 -1-SO 2 , and fcS 2 -2-SO show that, with respect to fcS 3 , the progressive oxidation of the trisulfane bridge makes more and more difficult the fc/fc + oxidation, whereas insertion of a Cp 2 Ti fragment exerts the opposite effect.
