Sulfido complexes

Interesting new sulfido complexes of tin have been prepared by the reaction of styrene sulfide with the N-alkylated tin(II) amidinate complexes Sn[RC(NCy)2]2 (Cy = cyclohexyl R = Me, Bu ). The products exhibit two very different bonding modes for the sulfido ligands in one case, S = Sn[RC(NCy)2]2/ a terminal Sn = S moiety was found while in the other case the bridging... 

The reaction of [p-MeC6H4C(NSiMe3)2]2Ta( = CH2)CH3 with 2,6-dimethyl-phenyl isocyanide afforded an f/ -ketenimine complex (Scheme 118). Carbon-sulfur cleavage reactions produced tantalum thioformaldehyde and tantalum sulfido complexes. ... 

Technetium(V) complexes with terminal main groups other than oxo are very rare. The terminal [M=S] group is isoelectronic with [M=0], but as expected is much more sensitive towards hydrolysis. The Tc sulfido complexes [TcS(edt)2] (224) and [TcSCl2(HB(pz)3)] are prepared by methods known from Mo or Re chemistry. Blood-red (224) is made from the Tc complex [TcCle] (69) in the presence of a tenfold excess of (83), while the sulphido complex... 

Some typical M—S distances for thioanions are given in Table 1. For J(Nb—S) and d(Ta—S) in sulfido complexes, examples have only recently been reported. rf(Nb—Swrm) = 2.09-2.13 A... 

Aliphatic thiolates often show C—S bond cleavage as shown in equation (2).107 The C—S fission reaction often tends to generate rather unreactive sulfido-bridged species, but sometimes, as in the given example, a mononuclear sulfido complex is produced.
