fac-Trichloro(quinolin-8-ylimido-N,N')(triphenylphosphine-P)rhenium(V)

The Re atom in [Re(C(9)H(6)N(2))Cl(3)(C(18)H(15)P)] is octahedrally coordinated by three Cl atoms in facial positions, two N atoms from 8-imidoquinoline (imq) and one P atom from triphenylphosphine. The Re-N(imido) distance [1.760 (9) and 1.772 (8) A] for imq is very short and implies double-bond character. The trans influence of the P atom is indicated. Intra- and intermolecular pi-pi interactions between the pi-rings in the complex are also observed.
