Undeca-carbon-yl[(4-methyl-sulfanylphen-yl)di-phenyl-phosphane]triruthenium(0): crystal structure and Hirshfeld surface analysis.

The title cluster compound, [Ru(CHPS)(CO)], comprises a triangle of Ru atoms, two of which are bonded to four carbonyl ligands. The third metal atom is bound to three carbonyl ligands and the phosphane-P atom of a dissymmetric phosphane ligand, PPh(CHSMe-4); no Ru⋯S inter-actions are observed. The phosphane occupies an equatorial position and its proximity to an Ru-Ru edge results in the elongation of this bond with respect to the others [2.8933 (2) Å . 2.8575 (2) and 2.8594 (3) Å]. In the crystal, phenyl-C-H⋯O(carbon-yl) and carbonyl-O⋯O(carbon-yl) [2.817 (2) Å] inter-actions combine to form a supra-molecular chain propagating along [111]; the chains pack without directional inter-actions between them. The carbonyl-O⋯O(carbon-yl) and other weak contacts have an influence upon the Hirshfeld surfaces with O⋯H contacts making the greatest contribution, . 37.4% . 15.8% for O⋯O and 15.6% for H⋯H contacts.
