Abstract

The cis-isomer of di-µ-carbonyl-dicarbonyldi-π-cyclopentadienyldi-iron has been isolated by low-temperature crystallisation and its structure determined by a single-crystal X-ray analysis. The crystals are monoclinic, a= 8·880(2), b= 12·301(3),c= 13·140(3)Å, β= 108·64(1)°. The space group is P21/c with Z= 4. After least-squares refinement with over 1500 observations R is 0·051. The i.r. spectrum of the complex has been measured in the ranges 200–1000 and 1600–2000 cm.–1 and assignments have been suggested. Study of the 1H n.m.r. spectra of the cis- and trans-isomers as a function of temperature confirms that solutions of the complex contain both isomers. Mössbauer and mass-spectral data are also presented.
