Abstract

The 100-MHz pmr and infrared spectra between 1700 and 2100 cm-1 of [(h5-C5H5)Fe(CO)2]2 and [(h5-C5H5)Ru(CO)2]2 have been investigated as functions of solvent and temperature. There are four isomers present in solutions of the ruthenium compound: cis bridged (I), trans bridged (III), trans nonbridged (IV), and a polar nonbridged structure (probably V). The thermodynamic and kinetic data measured in nonpolar solvents are consistent with the nonbridged isomers as intermediates in the interconversion of I and III. The approximate kinetic activation parameters for the I ⇄ III process in the iron compound have been evaluated from the temperature dependence of the pmr spectrum.
