INORGANIC CHEMISTRY

Our most intensive efforts are being applied to the synthesis, reaction studies and structural characterization of transition metal complexes containing pentadienyl ligands. These ligands seem interesting as they can be considered to be ??opened?? cyclopentadienyl ligands. One might therefore expect that a large area of chemistry would exist wherein a pentadienyl ligand replaces its more familiar cyclic coun
