Unusual coordination modes of arylthiolates in Mo(eta(5)-SC(6)H(3)-2,6-(SiMe(3))(2))(eta(7)-SC(6)H(3)-2,6-(SiMe(3))(2)).
Treatment of MoCl(3)(thf)(3) with LiSC(6)H(3)-2,6-(SiMe(3))(2) (LiSAr) resulted in formation of the pi-sandwiched bis-arylthiolato complex, Mo(eta(5)-SC(6)H(3)-2,6-(SiMe(3))(2))(eta(7)-SC(6)H(3)-2,6-(SiMe(3))(2)) (1), while the analogous reaction with LiSC(6)H(3)-2-Ph-6-SiMe(3) afforded the trithiolate complex Mo(SC(6)H(3)-2-Ph-6-SiMe(3))(3) (3). The acetonitrile adduct Mo(SAr)(2)(CH(3)CN)(3) (2) was isolated from the CH(3)CN solution of 1, in which one acetonitrile is coordinated to the metal center in an eta(2)-fashion. Structures of 1, 2, and 3 have been determined by X-ray diffraction.
