Crystal structures of o-, m,- and p-nitrophenylferrocenes and their relevance to other sterically crowded phenylferrocenes

“…Supporting this is the greatly reduced basicity of the compound. 26 The bond lengths of the conjugated cp ring are seen to be all equal within experimental error [average 1.431 (7) A]. This is in striking contrast to all the structures of monosubstituted ferrocenes where the substituents are electron withdrawing ( -M).…”

Key multi(ferrocenyl) complexes in the interplay between electronic coupling and electrostatic interaction

“…60 Tris(ferrocenyl)amine (37) showed three well-resolved reversible oxidation waves within CV experiments in acetonitrile with NaClO 4 . 62 This is an unusual molecule, as shown by its molecular structure, 63 since it contains three ferrocenyl groups surrounding the nitrogen atom in an almost planar conformation. In addition, the short C(ring)-N bonds (average 1.414 Å) indicate partial double-bond character between the nitrogen and the cyclopentadienyl ring suggesting the existence of a strong electronic interaction between the nitrogen and the ferrocenyl substituents, resulting in resonance interaction as an important factor in the stabilization of the ferrocenium by nitrogen.…”
