A mixed-valence chloride-bridged (pincer)IrIII-(diene)IrI complex

The title compound, [2,6-bis(di-tert-butylphosphino)phenyl-1 kappa P-3,C-1,P']di-mu-chlorido-1:2 kappa Cl-4:Cl-(2 eta(4)-cycloocta-2,5-diene)-hydrido- 1 kappa H-diiridium(I,III) hexane hemisolvate, [Ir-2(C8H12)-( C24H43P2)Cl2H]center dot 0.5C(6)H(14) or [((PCP)-P-tBu)IrH(mu(2)-Cl)(2)Ir(COD)]-[ (PCP)-P-tBu is kappa(3)-2,6-((Bu2PCH2)-Bu-t)(2)C6H3 and COD is eta(4)-2,5-cyclooctadiene], is an Ir-III/Ir-I dimer bridged by two chloride ions. The Ir2Cl2 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.
