Abstract

The title compound, [2,6-bis-(di-tert-butyl-phosphino)phenyl-1³ P,C ¹,P′]di - chlorido-1:2⁴ Cl:Cl-(2 ⁴-cyclo-octa-2,5-diene)hydrido-1H-diiridium(I,III) hexane hemisolvate, [Ir2(C8H12)(C24H43P2)Cl2H]·0.5C6H14 or [( ^tBuPCP)IrH(2-Cl)2Ir(COD)][^tBuPCP is ³-2,6- (^tBu2PCH2)2C6H3 and COD is ⁴-2,5-cyclo-octa-diene], 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)° between the two Ir centers. The compound was isolated as a hexane hemisolvate. A list of distances found in Ir(PCP) compounds is given.
