Carbonylchlorido(1-methylsulfanylpenta-1,3-dien-1-yl-5-ylidene)bis(triphenylphosphane)osmium(II)

چکیده
The crystal structure of the title compound, [Os(C(6)H(7)S)Cl(C(18)H(15)P)(2)(CO)], confirms the formulation as an osmabenzene. There is a slightly distorted octa-hedral coordination environment at the Os(II) ion, with the triphenyl-phosphane ligands mutually trans and the chloride cis to the carbon bearing the -SMe substituent. Within the metallacyclic ring, the C-C distances are appropriate for aromatic bonds and the two Os-C distances are shorter than typical Os-C single bonds. The maximum deviation from the least-squares plane through the osmabenzene ring occurs for the carbon bearing the SMe substituent [0.1037 (18) Å].

In the title binuclear complex, [Li2(C27H36N2)2I2], the unique Li(I) cation is coordinated by two iodide anions and one yl-idene C atom from a 1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene ligand in a distorted trigonal-planar geometry. The two symmetry-related iodide anions bridge two Li(I) cations, forming an inversion dimer in which the Li2I2 plane is nearly perpendicular to the imid...
