MOLECULAR AND VALENCE STRUCTURES OF COMPLEXES OF CYCLOOCTATETRAENE WITH IRON TRICARBONYL
Abstract
Structure determinations by X-ray diffraction methods indicate that Fe(CO)3 units are bonded to a butadiene type of residue in C8H8Fe(CO)3(I), and in (OC)3FeC8H8Fe(CO)3 (II), where the two Fe(CO)3 units are on opposite sides of the C8H8 ring. The dihedral C8H8 ring in (I) and the chair C8H8 ring in (INES, *Cyclo octatetraene, Monocyclic compounds, Carbonyl radicals, Single crystals, Crystal structure, Valence, Chemical bonds. Structure determinations by X-ray diffraction methods indicate that Fe(CO)3 units are bonded to a butadiene type of residue in C8H8Fe(CO)3(I), and in (OC)3FeC8H8Fe(CO)3 (II), where the two Fe(CO)3 units are on opposite sides of the C8H8 ring. The dihedral C8H8 ring in (I) and the chair C8H8 ring in (II) are previously unknown and unsuspected geometries for cyclooctatetraene. Crystals of (I) have symmetry Pnam, within ex perimental error, with four molecules in a unit cell defined by the parameters a = 6.54, b = 13.46, c = 11.50 angstroms. Crystals of (II) are of symmetry P2 sub 1/n, with four molecules in a unit cell which has parameters a = 12.52, b = 13.38, c = 8.86 and beta = 111 degrees. The bonding of Fe to the butadiene-like resi ues is discussed.
