(4-{[(Pyridin-4-yl)methylidene]amino}phenyl)ferrocene

Abstract

The asymetric unit of the title compound, [Fe(C5H5)(C17H13N2)], contains two independent molecules whose conformations differ, especially in the 4-{(pyridin-4-yl)methylidene]amino}phenyl unit where one is flipped by almost 180°. The cyclopentadienyl rings of the ferrocene unit also exhibit different staggered conformations: in one molecule the conformation is staggered by 9.43 (2)° and in the other by 24.46 (1)° from an ideal eclipsed geometry. The plane of the benzene ring is tilted away from the ferrocene group in both molecules, with dihedral angles of 6.97 (1) and 10.30 (2)°. The benzene ring is also slightly twisted from the plane of the pyridine ring, with dihedral angles of 5.98 (2) and 6.51 (2)° in the two molecules

“…21,64 The ferrocenyl-N-(pyridinylmethylene)anilines 3-8 were synthesized by grinding ferrocenylaniline, compound 1 or 2 in combination with apposite pyridinecarboxaldehyde in a pyrex tube fitted with ground joint and a side arm. 65 Grinding for 2-10 min resulted in a paste or in some cases a gummy melt that was dried under reduced pressure to get product as a dry solid. All the physical and spectral data for the known compound, 4-pyridylimine-4'-phenylferrocene (5), i.e.…”
