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 iron o-pyridyl-ethynyl complex Cp(CO)₂Fe-C≡C-(2-C₅H₄N). The Fe and Pd atoms in FePd1 are bridged by carbonyl and pyridyl-vinyl-idene ligands, the pyridyl N atom being bonded to the palladium atom. The use of equimolar amounts of PdCl₂ increases the yield of FePd1 to 12%. The reaction pathway leading t
