title: A mixed-valence chloride-bridged (pincer)Ir(III)-(diene)Ir(I) complex.
abstract: The title compound, [2,6-bis(di-tert-butylphosphino)phenyl-1kappa(3)P,C(1),P']di-mu-chlorido-1:2kappa(4)Cl:Cl-(2eta(4)-cycloocta-2,5-diene)hydrido-1kappaH-diiridium(I,III) hexane hemisolvate, [Ir(2)(C(8)H(12))(C(24)H(43)P(2))Cl(2)H].0.5C(6)H(14) or [((tBu)PCP)IrH(mu(2)-Cl)(2)Ir(COD)][(tBu)PCP is kappa(3)-2,6-((t)Bu(2)PCH(2))(2)C(6)H(3) and COD is eta(4)-2,5-cyclooctadiene], is an Ir(III)/Ir(I) dimer bridged by two chloride ions. The Ir(2)Cl(2) framework is nearly planar, with a dihedral angle of 13.04 (4) degrees between the two Ir centers. The compound was isolated as a hexane hemisolvate. A list of distances found in Ir(PCP) compounds is given.
