Six- and five-co-ordinate complexes of ruthenium(II) with the unsymmetrical diphosphine ligand Ph2P(CH2)3PMe2 have been prepared.Phosphorus-31 n.m.r. spectroscopy indicates that octahedral complexes , , and ClO4 (P-P = diphosphine ligand) have the all-trans arrangement with Me2P trans to Me2P and Ph2P trans to Ph2P.The five-co-ordinate complexes BPh4, where X = Cl or H, are not fluxional at room temperature and have a trigonal-bipyramidal structure with axial PMe2 groups and equatorial PPh2 groups.Similar structures are proposed for analogous complexes of Ph2P(CH2)3PMePh and of Ph2P(CH2)3PPh2.
