[1,3-Bis(di­phenyl­phosphino)prop­ane]­tri­chloro­oxorhenium(V)

Tri­chloro­oxo­[1,3-prop­ane­diyl­bis­(di­phenyl­phosphine)-P,P′]rhen­ium(V), [Re­Cl₃­O­(C₂₇­H₂₆P₂)], crystallizes with four formula units per unit cell. The crystal structure consists of neutral complexes of [ReOCl₃(dppp)] [dppp is 1,3-bis(diphenylphosphino)propane] packed by H⋯π-ring interactions. The Re atom is octahedrally coordinated to the oxo anion, three Cl atoms and two P atoms from the dppp ligand. The six-membered ring formed by the bidentate dppp ligand and the rhenium metal centre is in a chair conformation. The title compound is an intermediate in the synthesis of bis(dppp) complexes of rhenium.
