 Title    Übergangsmetall-Komplexe mit Schwefelliganden, XXVII* Synthese und Reaktivität der Nitrosyl-und Nitrido-Ruthenium-Komplexe mit 1,2-Benzoldithiolat-Liganden [Ru(NO)(S 2 C 6 H 4 ) 2 r bzw. [Ru(N)(S 2 C 6 H 4 ) 2 r Transition Metal Complexes with Sulfur Ligands, XXVII* Synthesis and Reactivity of the Nitrosyl-and Nitrido-Ruthenium Complexes with 1,2-Benzenedithiolate Ligands [Ru(NO)(S 2 C 6 H 4 ) 2 ]~ and [Ru(N)(S 2 C 6 H 4 ) 2 ]~, Respectively  
 Abstract    The reaction of [Ru(NO) 2 (PPh 3) 2 ], [RuCl(NO) 2 (PPh 3) 2 ]PF 6 or [RuCl 3 (NO)(PPh 3) 2 ] with 1,2-benzenedithiolate(—2), C 6 H 4 S 2 : ~, leads to the 16e"-complex [Ru(NO)(S 2 C 6 H 4) 2 ]~, which was isolated as the NBu 4 + salt (1). The square pyramidal anion in [NBu 4 ][Ru(NO)(S 2 C 6 H 4) 2 ] coordi-nates PMe 3 with rearrangement of the sulfur ligands to give the six-coordinate cis-[NBu 4 ][Ru(NO)(PMe 3)(S 2 C 6 H 4) 2 ] (3); the rearrangement of the C 6 H 4 S 2 2 "-ligands from trans to eis coordination is proved by 13 C NMR spectroscopy. [Ru(NO)(S 2 C 6 H 4) 2 ]~ is rapidly reduced even under mild conditions. Reaction of 1 with NaBH 4 in MeOH leads to the reduction of NO to a nitrido ligand and the concomitant oxidation of (formal) Ru(III) to Ru(VI) yielding [NBu 4 ][Ru(N)(S^C 6 H 4)->] (2). This compound is also formed when the nitrosyl complex is reacted with SiMe 3 N 3 . [Ru(NO) 2 (PPh 3) 2 ] and [RuCl(NO) 2 (PPh 3) 2 ]PF 6 are denitrosylatedby dttd 2 ~ (dttd 2 " = 2,3,8,9-dibenzo-l,4,7,lÖ-tetrathiadecane(—2)) to give [Ru(dttd)(PPh 3) 2 ],
