dc.description.abstractReaction of diphosphine complexes [IrCl{(C6F5)(2)P(CH2)(2)P(C6F5)(2) }](2) (I) and [IrCl(dppe)](2) (II) with coordinating solvents (acetonitrile, acetone, DMSO) leads to several square-planar complexes of the type [IrCl(diphosphine)(solvent)] which are stable only in solution ([IrCl{(C6F5)(2)P(CH2)(2)P(C6F5)(2)}(NCCH3)] (III) and [IrCl{(C6F5)(2)P(CH2)(2)P(C6F5)(2)} (acetone)], IV) and/or can be detected only under APCI-MS/MS conditions ([IrCl(dppe)(solvent)]). When III is allowed to react with CO for at least 30 min, the unusual five coordinated trans-dicarbonyl complex [IrCl{(C6F5)(2)P(CH2)(2)P(C6F5)(2)}(CO)(2)] (Vb) is formed, as characterized by H-1 and P-31 NMR, FT-IR, TGA and APCI-MS/MS. A new and stable square-planar complex [Ir(OCH3)(cod)(PClPh2)] (IX) was also synthesized. Its APCI-MS/MS spectrum is simple and unique as it shows exclusively the loss of a neutral C3H2 species. Along with the APCI-MS and APCI-MS/MS analyses, whenever it was possible all complexes were also characterized by H-1 and P-31 NMR spectroscopy. (C) 2003 Elsevier B.V. All rights reserved.pt
