Pentacarbonyl[ethoxy(2-ethoxy-4,5-diphenyl-1,3-cyclopentadienyl)carbene]chromium(0)

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-CCO bond trans to the Cr=C carbene bond is significantly shorter than the equatorial Cr-CCO bonds.
