Abstract

original image

The rotation of the C7H7, bridge ligand of 1 is already frozen-in on the NMR time scale. 1 is the first syn-μ-cycloheptatrienyl complex in which this has been observed. It also contains the first CrHCo bridge to be structurally analyzed, which has bond lengths of 1.69 and 1.54 Å and subtends an angle of 127°.
