Coordination complexes of chromium(0) with a series of 1,3-diphenyl-6-aryl-fulvenes.

ABSTRACT: The synthesis and structural properties of a series of chromium tricarbonyl 'piano-stool' complexes bearing substituted penta-fulvene ligands were studied. The complexes, tricarbon-yl(1,3,6-tri-phenyl-fulvene)chromium(0) benz-ene hemisolvate, [Cr(C₂₄H₁₈)(CO)₃]·0.5C₆H₆ (I), tricarbon-yl[1,3-di-phen-yl-6-(3-vinyl-phen-yl)fulvene]chromium(0), [Cr(C₂₆H₂₀)(CO)₃] (II), and tricarbon-yl[1,3-diphenyl-6-(pyren-1-yl)fulvene]chromium(0), [Cr(C₃₄H₂₂)(CO)₃] (III), each have a distorted octa-hedral geometry, with the fulvene coordinated in a π-η²:π-η^2:π-η² fashion. Significant deviation of the exocyclic fulvene double bond from the
