[μ-Bis(diphenyl-arsino)methane-1:2κAs:As']nona-carbonyl-1κC,2κC,3κC-[diphen-yl(phenyl-sulfanylmeth-yl)phosphine-3κP]-triangulo-triruthenium(0) chloro-form hemisolvate.

ABSTRACT: The asymmetric unit of the title triangulo-triruthenium cluster, [Ru(3)(C(25)H(22)As(2))(C(19)H(17)PS)(CO)(9)]·0.5CHCl(3), contains of one mol-ecule of the triangulo-triruthenium complex and half a mol-ecule of the disordered (two positions of equal weight) chloro-form solvent. The bis-(diphenyl-arsino)methane ligand bridges an Ru-Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru(3) triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The benzene ring of phenyl-thio-methyl is disordered over two positions with refined site occupancies of 0.788 (11) and 0.212 (11). In the crystal packing, mol-ecules are linked into chains along b axis by inter-mol
