摘要：

The cluster CP'2Mo2Co2S3(CO)4 (1; CP' = C5H4Me) reacts with trimethylphosphine to form the adduct CP'2Mo2Co2S3(CO)4(PMe3) (2a), in which a Co-S bond has been cleaved. Methyl isocyanide forms a similar adduct, CP'2Mo2Co2S3(CO)4(MeNC) (2b), at <0-degrees-C but loses CO to form the carbonyl-substituted cluster CP'2Mo2Co2S3(CO)3(MeNC) (3) at higher temperatures. Reaction of 1 with CO at high pressure (1450 psi) was shown to give reversibly the pentacarbonyl cluster CP'2Mo2Co2S3(CO)5 (2c). Crystal data for 2a: space group Pn; Z = 4; a = 7.089 (1) angstrom, b = 18.669 (6) angstrom, c = 18.469 (4) angstrom, beta = 90.84 (2)-degrees, T = -100-degrees-C, V = 2448 (1) angstrom3, R = 0.0404, R(w) = 0.0500 based on 4739 reflections with F(o) greater-than-or-equal-to 5-sigma(F).
