1,5-Bis[(E)-1-(2-hydroxyphenyl)ethyl­idene]thiocarbonohydrazide mono­hydrate

In the title compound, C(17)H(18)N(4)O(2)S·H(2)O, the thio­urea derivative is almost planar, with an r.m.s. deviation for the non-H atoms of 0.057 Å. The hydroxyl groups lie to the same side of the mol­ecule as the thione S atom, a conformation that allows the formation of intra­molecular O—H⋯S and O—H⋯N hydrogen bonds. In the crystal structure, the thio­urea and water mol­ecules self-assemble into a two-dimensional array by a combination of O(water)—H⋯O(hydrox­yl), N—H⋯O(water) and O(water)—H⋯S hydrogen bonds and C—H⋯π inter­actions.
