title: N'-(4-Hy-droxy-benzyl-idene)ferrocene-1-carbohydrazide.
abstract: In the title compound, [Fe(C(5)H(5))(2)(C(13)H(11)N(2)O(2))], the dihedral angle between the benzene ring and the cyclo-penta-diene ring bonded to the carbonyl group is 26.1 (2)°. In the crystal, bifurcated O-H⋯(O,N) and N-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
