Crystal structures of four new iridium complexes, each containing a highly flexible carbodi-phos-phorane PCP pincer ligand.

ABSTRACT: Compound [Ir(C₈H₁₂)(C₅₁H₄₅P₄)]Cl₂ or [Ir(cod)(CH(dppm)₂-κ³P,C,P)]Cl₂ (1a), was obtained from [IrCl(cod)]₂ and the carbodi-phospho-rane (CDP) salt [CH(dppm)₂]Cl [where cod = cyclo-octa-1,5-diene and dppm = bis-(di-phenyl-phosphino)methane]. Treatment of 1a with thallium(I) tri-fluoro-methane-sulfonate [Tl(OTf)] and subsequent crystallization gave complex [Ir(C₈H₁₂)(C₅₁H₄₅P₄)](OTf)₂·CH₃CO₂C₂H₅·CH₂Cl₂ or [Ir(cod)(CH(dppm)₂-κ³P,C,P)](OTf)₂·CH₃CO
