“…The reaction of [Ru 3 (CO) 12 ] with 0.5 mol of 2-mercaptopyridine (HSpyH) in THF at reflux temperature lead to a mixture of products, from which the dark green BEBSP hexanuclear derivative [Ru 6 (μ 3 -H)(μ 5 -κ 2 -SpyH)(μ-CO)(CO) 15 ] ( 16 ) could be separated by chromatographic methods (38% yield) (Scheme ) . The trinuclear thiolato cluster [Ru 3 (μ-H)(μ 3 -κ 2 -SpyH)(CO) 9 ] , has been observed as a transient intermediate when the reaction is monitored by IR spectroscopy and spot TLC.…”

This paper reviews the current knowledge on the synthesis, structure, and reactivity of basal-edgebridged square-pyramidal hexaruthenium carbonyl cluster complexes, covering the literature up to the end of 2007. These clusters are generally prepared at high temperature (>100 °C) through processes that involve a ligand-promoted condensation of two triruthenium clusters. All cluster complexes of this type contain a bridging ligand with an S-, C-, or N-donor fragment capping the four basal metal atoms of the pyramid. When the bridging ligand is bi-or polydentate, it is also bound to the edge-bridging metal atom. The reactivity of [Ru 6 (µ 3 -H) 2 (µ 5 -κ 2 -ampy)(µ-CO) 2 (CO) 14 ] (H 2 ampy ) 2-amino-6-methylpyridine) with various reagents has been recently investigated. Its reactions with unsaturated hydrocarbons (carbocycles, alkynes, diynes, alkenes) often involve multisite coordination and hydrogenation or dehydrogenation of the original reagents. The release of an Ru(CO) n fragment (the only one that is not bound to the bridging ampy ligand) or its exchange between hexanuclear species is also frequently observed. This leads to penta-and heptanuclear clusters as final products. The reactivity of [Ru 6 (µ 3 -H) 2 (µ 5 -κ 2 -ampy)(µ-CO) 2 (CO) 14 ] with other reagents (triphenylphosphine, hydrides, H 2 ampy) and its thermolysis in solution are also surveyed.

“…In contrast with the sulfido derivative 2 , which has no hydrides, and the imido derivatives 11 − 15 , which have two hydrides, the thiolate clusters 16 and 17 contain one hydride ligand capping a face of the pyramid. Their cluster shell is completed by 1 edge-bridging and 15 terminal CO ligands …”

“…2-mercaptopyridine, its 6-methyl substituted and N-oxide derivatives have exhibited rich coordination motifs. They can serve as monodentate (Hamaguchi et al, 2007;Chunchuryukin et al, 2006), bidentate (Cotton et al, 1978;West et al, 1998;Fielding et al, 1997;Berardini et al, 1997), and bridging (Tylicki et al, 1995;Hong, et al, 1999;Cabeza, et al, 2007) ligands to coordinate metals. Though syntheses and crystal structures of these metal complexes have been reported, the crystal structure of 2-mercapto-6-methylpyridine itself has not been yet reported.…”

Key indicators: single-crystal X-ray study; T = 295 K; mean (C-C) = 0.003 Å; R factor = 0.043; wR factor = 0.148; data-to-parameter ratio = 20.2.There are two unique molecules in the asymmetric unit of the title pyridinethione derivative, C 6 H 7 NS, each of which adopts the thione rather than the mercaptan form. The rings in both molecules are essentially planar, with maximum deviations from the least-squares planes through all non-H atoms of 0.021 (2) and 0.017 (2) Å . In the crystal structure, the molecules form centrosymmetric cyclic dimers through intermolecular N-HÁ Á ÁS hydrogen bonds. Additional C-H(methyl)Á Á ÁS interactions generate a three-dimensional network. Related literature
