Bonding in Organometallic Molecules containing a Cyclopentadienone Ligand

Abstract

CYCLOPENTADIENONE complexes of several transition metal ions have been prepared by the reaction of hexa-fluoro-but-2-yne with the metal carbonyl or π-cyclopentadienyl metal carbonyl1. Detailed crystal structure analyses have now been made of π-cyclopentadienyl-tetrakis (trifluoromethyl) cyclopentadienone cobalt and tetrakis (trifluoromethyl) cyclopentadienonetricarbonyl iron by Patterson, Fourier and least-squares methods. The conventional discrepancy indices are 0.088 and 0.110 respectively, refinement still proceeding in the latter case.
