چکیده
In the title mol-ecule, C(10)H(13)N(3)O(3)S·2H(2)O, the thio-semi-carbazide =N-NH-C(=S)-NH- fragment [torsion angle = 0.2 (1)°] is nearly coplanar with the benzene ring [dihedral angle = 2.4 (1)°]. The benzene ring and semicarbazide moiety are located on opposite sites of the C=N bond, showing an E configuration. The hy-droxy, imino and water H atoms are engaged in extensive hydrogen bonding, forming a three-dimensional network.
