The title compounds, 1-ferrocenylmethyl-2-(4-methoxyphenyl)-1H-benzimidazole,[Fe(C5H5)(C20H17N2O)], (I), and
2-(3,4-dimethoxyphenyl)-1-ferrocenylmethyl-1H-benzimidazole,
[Fe(C5H5)(C21H19N2O2)], (II), are model electroactive
compounds for anion sensor and antimalarial applications.
Distortions from the ideal 120 angle about the MeO--C--C
groups are evident, with angles of 115.1(2) and 125.0(2) in (I), and 115.9(2) and 124.6(2), and 115.7(2) and 125.1(2) in (II). The main intermolecular hydrogen bonds in (I) comprise C--H...N and C--H...pi(C5H5) interactions, while in (II), only weak C--H...(imidazole) and C--H...pi(arene) interactions are present.
