Crystal and molecular structure of µ-carbonyl-µ-(1–3-η : 1-σ, 4–2′-η-{1,3-dimethyl-4-[5-oxo-4-phenyl-2(5H)-furan-2-ylidene]but-1-ene-1,3-diyl})-bis(dicarbonylcobalt)(Co–Co)

Abstract

The crystal and molecular structure of the title compound have been determined by X-ray diffraction methods from photographic data. Crystals are triclinic tablets, space group P1, with Z= 2 in a cell with dimensions a= 9.41(3), b= 9.98(3), c= 11.90(3)Å, α= 97.3(3), β= 100.9(3), and γ= 108.3(3)°. The structure has been solved by Patterson and Fourier methods, and refined by least-squares techniques to R 0.096 for 946 reflections. The cobalt–cobalt distance is 2.48 Å.
