R factor = 0.033; wR factor = 0.084; data-to-parameter ratio = 16.7. In the title molecule, [Ru(C9H7)(C7H5O)(CO)2], the dihedral angle between the mean plane of the indene ring system and the phenyl ring is 86.28 (8). The crystal structure is stabilized by weak intermolecular C—H O and C—H (arene) interactions. The Ru—5-cyclopentadienyl centroid bond length is 1.946 (11) Å Related literature For background information, see: Chung et al. (1982). For th
