Carbon compounds of the transition metals. Part XIII. Evidence for, and crystal structure of, octacarbonyldiphenylvinylidenedi-iron

Abstract

The orange compound formed during the irradiation of a benzene solution of diphenylketen and pentacarbonyliron is shown by X-ray structural and mass spectroscopic methods to be octacarbonyldiphenylvinylidenedi-iron in which the diphenylvinylidene group is the sole bridge between two Fe(CO)₄ units. The nature of this unique arrangement with iron is discussed.
