摘要
The dimeric complex [Mn-2(mu-pyS)(2)(CO)(6)] (1) reacted with 2 M equivalents of both PPh3 and PHPh2 to give the respective monomeric phosphine complexes [Mn(pyS)(L)(CO)(3)][L = PPh3 (2) and PHPh2 (3)]; with 4 M equivalents of dppm, it yielded the complex [Mn(pyS)(eta(1)-dppm)(2)(CO)(2)] (4). An X-ray structure determination of 4 shows that it crystallizes in the monoclinic space group P2(1)/n with a = 11.027(3), b = 24.984(7), c = 18.379(5) Angstrom, beta = 99.870(8)degrees, V = 4988(2) Angstrom(3), and Z = 4. The complex has an octahedral geometry with the chelating pyS ligand and two CO groups occupying the equatorial sites and the two monodentate dppm ligands lying in the trans positions.
