名称:
A novel octa-substituted iridium carbonyl derivative containing the dehydrogenated dppf ligand (dppf=Fe(C5H4PPh2)2): synthesis and crystal structure of [H4Ir4(CO)4{Fe(C5H3PPh2)(C5H4P(Ph)C6H4)}2]
摘要:
The octa-substituted iridium carbonyl derivative [H4Ir4(Co)(4){Fe(C5H3PPh2) (C5H4P(Ph)C6H4)}(2)] prepared from [Ir-4(CO)(12)] and dppf consists of a tetrahedral Ir-4 unit and two tetradentate dehydrogenated dppf ligands formed upon ortho-metallation of a cyclopentadienyl and a phenyl ring with each iridium atom coordinated by a carbonyl group, a phosphorus and an ortho-carbon of the dehydrogenated cyclopentadienyl or phenyl group.
