Monoclinic form of (Z)-1-ferrocenyl-3-(3-hydroxyanilino)but-2-en-1-one

Abstract

The title compound, [Fe(C5H5)(C15H14NO2)], is a monoclinic polymorph of the previously reported triclinic form [Shi et al. (2006). Acta Cryst. C62, m407–m410]. The polymorphs feature the same strong intramolecular N—H...O=C hydrogen bonds, but show different packing modes. The molecules in the monoclinic form associate into double chains via O—H...O=C and (Cp)C—H...O—H interactions.
