1-Ferrocenylmethyl-2-phenyl-1H-1,3-benzimidazole

Abstract

In the title molecule, [Fe(C5H5)(C19H15N2)], the five‐membered C3N2 imidazole ring forms dihedral angles of 84.71 (13) and 52.12 (11)°, respectively, with the substituted cyclopentadienyl and phenyl rings. In the crystal structure, in addition to a weak C—H...N interaction, there is a modest C—H...π(ring) interaction involving a C—H group of the unsubstituted cyclopentadienyl ring and the imidazole ring.

“…The two exocyclic C-C-O angles at atom C33 (Table 2) differ by almost 10 . This behaviour seems to be typical for methoxyarene systems where the methoxy C atoms lies in, or close to, the plane of the arene ring (Seip & Seip, 1973;Ferguson et al, 1996;Gallagher et al, 2001Gallagher et al, , 2004Peralta et al, 2007;Cuervo et al, 2009), and a similar pattern is observed for the exocyclic C-C-O angles at atom C44, consistent with the location of atom C34 close to the plane of the pyridine ring, as noted above. By contrast, the exocyclic C-C-O angles at atom C34 are almost identical, typical of such angles where the -C atom of the alkoxy substituent is significantly displaced from the plane of the adjacent ring (Peralta et al, 2007;Cuervo et al, 2009).…”
