In the title compound, [Fe(2)Zn(C(5)H(5))(2)(C(13)H(11)N(3)S)(2)]·H(2)O, the Zn(II) ion is in a distorted tetra-hedral geometry being coordinated by two thio-semicarbazone ligands via N and S atoms. One of the Cp rings is disordered over two positions with occupancies of 0.55 and 0.45. The dihedral angle between the substituted Cp rings is 56.1 (5)° and the two phenyl rings are orientated at a dihedral angle of 41.7 (4)°. In the crystal structure, inter-molecular O-H⋯S, N-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules into chains along the b axis. The structure is further consolidated by O-H⋯π inter-actions.
