Five-co-ordinate rhodium(I) complexes with three metal–olefin bonds
Abstract
One-to-one complexes of the ligands (o-styryl)3P and (o-styryl)3As with RhX (X = Cl, Br, I) have been prepared: their properties indicate a pentaco-ordinate trigonal bipyramidal structure with the three olefin groups occupying the three trigonal (C3), and the halogen and phosphorus (or arsenic) atoms the apical, positions.
