to investigate specific properties of metal sulfur centers, anionic and neutral [Ru(‘S 2 ’) 2 (PMe 3 ) 2 ] n (1: n =−1; 2: n =0; ‘S 2 ’ 2− =1,2-benzenedithiolate(2−)) were synthesized from RuCl 3 · x H 2 O, Na 2 ‘S 2 ’ and PMe 3 in the absence ( 1 ) or presence ( 2 ) of O 2 . X-ray structure determinations of (NMe 4 )[Ru(‘S 2 ’) 2 (PMe 3 ) 2 ]·CH 3 OH ( 1a ) (triclinic, P 1 , a =882.6(3), b =935.1(2)
