title: Crystal structure of μ-carbonyl-1:2κ2C:C-carbonyl-1κC-(1η5-cyclo-penta-dien-yl)iodido-2κI-[μ-2-(pyridin-2-yl)ethene-1,1-diyl-1κC1:2κ2N,C1]ironpalladium(Fe-Pd) benzene monosolvate.
abstract: The reaction of Cp(CO)2FeI with 2-ethynyl-pyridine under Sonogashira conditions [5% PdCl2(PPh3)2, 10% CuI, THF-NEt3(2:1)] afforded the title binuclear μ-pyridyl-vinyl-idene FePd complex (FePd1) as a benzene solvate, [FePd(C5H5)(C7H5N)I(CO)2]·C6H6, in a very low yield rather than the expected irono-pyridyl-ethynyl complex Cp(CO)2Fe-C≡C-(2-C5H4N). The Fe and Pd atoms inFePd1are bridged by carbonyl and pyridyl-vinyl-idene ligands, the pyridyl N atom being bonded to the palladium atom. The use of equimolar amounts of PdCl2increases the yield ofFePd1to 12%. The reaction pathway leading toFePd1is proposed.
