[μ2-Bis(diphenylphosphanyl)hexane]bis[undecacarbonyl-triangulo-triruthenium(3Ru—Ru)] hexane monosolvate: crystal structure and Hirshfeld surface analysis

Abstract

In the title cluster complex hexane solvate, [Ru6(C30H32P2)(CO)22]·C6H14, two Ru3(CO)11fragments are linked by a Ph2P(CH2)6PPh2bridge with the P atoms equatorially disposed with respect to the Ru3triangle in each case; the hexane solvent molecule is statistically disordered. The Ru...Ru distances span a relatively narrow range,i.e. 2.8378 (4) to 2.8644 (4) Å. The hexyl chain within the bridge has an all-transconformation. In the molecular packing, C—H...O interactions between cluster molecules, and between cluster and hexane solvent molecules lead to a three-dimensional architecture. In addition, there are a large number of C[triple-bond]O...π(arene) interactions 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.
