Abstract: | The complex molecule in the title compound, [Re(C9H6NS)Cl2O(C18H15OP)]·C3H6O, has distorted octahedral geometry. The Re=O bond occupies the position trans to the triphenylphosphine oxide O atom. The Re—Cl bond trans to the thiolate S atom is longer than that trans to the quinoline N atom, implying a stronger trans influence of the S atom. Intra‐ and intermolecular π–π interactions are also observed between the π rings in the complex. |
