N′-(4-Hy­droxy­benzyl­idene)ferrocene-1-carbohydrazide

In the title compound, [Fe(C₅H₅)₂(C₁₃H₁₁N₂O₂)], the dihedral angle between the benzene ring and the cyclo­penta­diene 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 mol­ecules into a three-dimensional network.
