Abstract

The reaction of 2,2′-bipyridine (bpy) with monomeric chromium(II) precursors was used to prepare the S = 1 complexes Cr(tBu-acac)₂(bpy) (1) and (η⁵-Cp)(η¹-Cp)Cr(bpy) (3), as well as the S = 2 compound Cr[N(SiMe₃)₂]₂(bpy) (4). The crystallographically determined bond lengths indicate that the bpy ligands in 1 and 3 are best regarded as radical anions, while 4 shows no structural evidence for electron transfer from Cr^II to the neutral bpy ligand.
