The Schiff base C10H13N3O2S is monoclinic, having unit cell parameters a = 9.788(1) Å, b = 9.615(1) Å, c = 12.605(1) Å, β = 108.41(1)° and V = 1125.56(2) Å3 and belongs to P21/n space group. The molecule is almost planar. The two hydroxyl groups present on the phenyl ring are involved in intermolecular H-bonding, which results in the stacking of molecules in the anti-parallel fashion leading an interesting network of channels. Besides this C–H⋯π and π–π (edge to edge) interactions appear to provide stability to the crystal lattice.
