L. K. Hansen

Abstract: The title compound, [Cr(C₂₂H₂₃O₂)(CO)₅], is shown to have a slightly distorted octahedral geometry around the Cr atom and a Cr=C carbene bond length of 2.111  (5)  Å, clearly showing double-bond character. The axial Cr-C_CO bond trans to the Cr=C carbene bond is significantly shorter than the equatorial Cr-C_CO bonds.
