title: cis-Dicarbonyl-cis-dichlorido-trans-bis(triphenylphosphine-kappaP)iridium(III) tetrafluoridoborate, formed by reaction of (cycloocta-1,5-diene)bis(triphenylphosphine)iridium tetrafluoridoborate with carbonyl fluoride in dichloromethane solution.
abstract: The reaction between carbonyl fluoride and [Ir(COD)(PPh(3))(2)]BF(4) (COD is cycloocta-1,5-diene) in dichloromethane solution affords the novel title iridium salt, [IrCl(2)(C(18)H(15)P)(2)(CO)(2)]BF(4). The cation lies across a twofold rotation axis in the space group P2(1)2(1)2 and its structure confirms the presence in a cis relationship of two metal-bound chlorides, while the phosphine ligands occupy a trans pair of sites. The anion also lies across a twofold rotation axis, and the F atoms are disordered over two sets of sites.
