title: Ethyl (Z)-4-ferrocenyl-2-(4-hy-droxy-anilino)-4-oxobutenoate.
abstract: In the title compound, [Fe(C(5)H(5))(C(17)H(16)NO(4))], the O=C-C=C-N mean plane is twisted with respect to the mean planes of the benzene and substituted cyclo-penta-dienyl rings by 44.2 (2) and 13.8 (3)°, respectively. Furthermore, the O=C-C=C-N mean plane and the O=C-O(ester) plane make a dihedral angle of 55.5 (6)°. Consistent with this large dihedral angle, the linking C-C bond [1.507 (6) Å] does not show any (delocalized) double-bond character.
