- Abstract
Six new complexes of tin(IV) halides with phosphorus-containing ligands have been fully characterized by single-crystal X-ray diffraction at low temperature. Three of the compounds, derived from the diphosphanes bis-(diphenylphosphino)methane or bis-(dicyclohexylphosphino)methane, have a novel zwitterionic structure, with five Cl ligands and one unidentate phosphorus-containing ligand on tin, together with a proton on the second phosphorus atom of the potentially bidentate ligand; these are Cl5Sn−P(Ph2)CH2PPh2H+ ( 1), Cl5Sn−OP(Ph2)CH2-PPh2H+ ( 2), and Cl5Sn−OP(cy2)CH2Pcy2H+ ( 3). The other three complexes have a bidentate donor attached to the SnX4 moiety; they comprise Cl4SnOP(Ph2)-(CH2)2PPh2O ( 4), a derivative of bis-(diphenylphosphino)ethane dioxide, I4SnOP(Ph2)CH2PPh2O ( 5), a similar derivative of bis-(diphenylphosphino)-methane dioxide, and the very unusual Br4SnAs-(Ph2)(CH2)2PPh2O ( 6), with coordination to tin by As and O. Since the starting material for the last compound was Ph2As(CH2)2PPh2, this result illustrates well the more facile oxidation of P(III) than As(III). © 2009 Wiley Periodicals, Inc.
