According to the X-ray structure determination the N−S bond (1.716 Å) is arranged perpendicular to the Ru−Ru axis (2.661 Å).</jats:p>

Binuclear Complexes of Ruthenium and Osmium Containing Metal Metal Bonds

“…However, products could be isolated after several days if the reaction was carried out in xylene under reflux. These were identified as the ruthenacyclopentadiene complexes (210). In general, further reaction was not observed, but for the complex where R 1 = R 2 = CF 3 and R 3 = R 4 = CO 2 Me, reaction with an excess of DMAD in xylene under reflux gave the 'four-alkyne' complex [Ru 2 Cp 2 {u.-C 8 (CF 3 ) 2 (CO 2 Me) 6 }] (211)*.…”

“…A mixed nitrogen-sulfur-bridged complex of type (103), [Ru 2 fti-SNBu ! )(CO) 6 ] (103) (M = Ru, X 2 = SNBu\ L = CO), has been synthesized by the reaction of [Ru 3 (CO)12 ] with S(NBu l ) 2 210. Phosphorus-and arsenic-bridged complexes of type (103) are also known.…”
