[μ-Bis(di-phenyl-phosphan-yl)hexa-ne]bis-[undeca-carbonyl--triruthenium(3 -)] hexane monosolvate: crystal structure and Hirshfeld surface analysis.

In the title cluster complex hexane solvate, [Ru(CHP)(CO)]·CH, two Ru(CO) fragments are linked by a PhP(CH)PPh bridge with the P atoms equatorially disposed with respect to the Ru triangle in each case; the hexane solvent mol-ecule is statistically disordered. The Ru⋯Ru distances span a relatively narrow range, . 2.8378 (4) to 2.8644 (4) Å. The hexyl chain within the bridge has an all- conformation. In the mol-ecular packing, C-H⋯O inter-actions between cluster mol-ecules, and between cluster and hexane solvent mol-ecules lead to a three-dimensional architecture. In addition, there are a large number of C≡O⋯π(arene) inter-actions in the crystal. The importance of the carbonyl groups in establishing the packing is emphasized by the contribution of 53.4% to the Hirshfeld surface by O⋯H/H⋯O contacts.
