title: N'-Ferrocenyl-2-hydroxy-benzohydrazide.
abstract: The title complex, [Fe(C(5)H(5))(C(13)H(11)N(2)O(3))], was prepared via self-assembly using ferrocenyl hydrazide and ethyl salicylate. The compound is potentially a tridentate ferrocene-based ligand. The conformation of the mol-ecule allows the formation of an intra-molecular N-H⋯O hydrogen bond involving the hydroxyl group. The CONHNHCO unit and the rings bonded to it are nearly coplanar. The crystal structure is stabilized by inter-molecular O-H⋯O(carbon-yl) and N-H⋯O(carbon-yl) hydrogen bonds.
