STABILIZATION AND REACTION BEHAVIOUR OF A TERMINAL PHOSPHIDO UNIT ON A MONONUCLEAR PT(II) CENTRE - SYNTHESIS AND X-RAY STRUCTURE OF A CATIONIC DIPHENYLPHOSPHINE COMPLEX [PT(C6H3(CH(2)NME(2))(2)-2,6)(PHPH(2))][OSO2CF3] AND A DIPHENYLPHOSPHIDO-BRIDGED

摘要

Reaction of diphenylphosphine with the complexes [Pt(NCN)(H2O)]X (NCN = C6H3(CH(2)NMe(2))(2)-2,6; X = BF4 (1a), OSO2CF3 (1b)) leads to substitution of the H2O ligand to afford the ionic Pt(II) complexes [Pt(NCN)(PHPh(2))]X (X = BF4 (2a), OSO2CF3 (2b)). The X-ray structure of the square-planar diphenylphosphine complex 2b is described; triclinic, space group P
