Abstract: The (benzylideneacetone)Fe(CO)2L complexes, with L = CO, PPh3, PMePh2, PMe2Ph, PEt3, PCy3, P(OPh)3, P(OMe)3, P(OEt)3 and P(OiPr)3 have been studied by Mössbauer spectroscopy. The spectra are compatible with a distorted octahedral geometry with the iron atom at the center. The isomer shifts δ and quadrupole splittings ΔEq are correlated with the Giering electronic parameter χd of the phosphines and phosphites and with the 13C NMR complex shifts ΔC4 of coordinated benzylideneacetone. The results are discussed in terms of the stereoelectronic effects of the ligand L. Correlation between isomer shifts and quadrupole splittings indicates that dπ-Lπ{black star} back bonding is predominant in the complexes with L = CO and phosphites and negligible in the complexes with L = phosphines. © 1994.
