Acenaphthylene (C12H8) reacts with ReH7(PCy3)2 (Cy = cyclohexyl) at 70°C to give a complex shown by 1H and 31P NMR and X-ray crystallography to be (η4-C12H10)ReH3(PCy 3)2. The molecule adopts a distorted pentagonal-bipyramidal structure with rhenium bound to four carbons of one six-membered ring. This compound is stereochemically rigid, showing three inequivalent hydride and two inequivalent phosphorus nuclei. Since the hydrocarbon ligand has had one double bond hydrogenated (the one not involved in the naphthalene framework) and since this ligand is not displaced by C12H8 under the reaction conditions, the hydrogenation appears to proceed by intramolecular hydrogen transfer. Crystal data (-158 °C): a = 18.920 (6) A?, b = 12.976 (3) A?, c = 18.685 (6) A?, β = 111.63 (1)°, and Z = 4 in space group P21/c.
