Matrix isolation studies of the bonding of acetyl groups in the co-ordinatively unsaturated species acetyltetracarbonylmanganese and acetylmonocarbonyl(η-cyclopentadienyl)iron
Abstract
The infrared band positions of νCO(acetyl) for [Mn(CO)4(COCH3)] and [Fe(η5-C5H5)(CO)(COCH3)] are reported in CH4 matrices at 12 K. It is proposed that the acetyl ligands have σ-acetyl type bonding in these co-ordinatively unsaturated species.
