1-(2,3,4-Trihydroxy­benzyl­idene)thio­semicarbazide

In the title mol­ecule, C(8)H(9)N(3)O(3)S, the thio­semicarbazide =N—NH—C(=S)—NH— fragment is twist a different degree of twist in the three independent mol­ecules [dihedral angles = 7.6 (1), 11.6 (1) and 20.7 (1)°]. Intra­molecular O—H⋯N and O—H⋯O hydrogen bonds occur. In the crystal, the hydr­oxy...

Sumario:In the title mol­ecule, C(8)H(9)N(3)O(3)S, the thio­semicarbazide =N—NH—C(=S)—NH— fragment is twist a different degree of twist in the three independent mol­ecules [dihedral angles = 7.6 (1), 11.6 (1) and 20.7 (1)°]. Intra­molecular O—H⋯N and O—H⋯O hydrogen bonds occur. In the crystal, the hydr­oxy and amino groups are hydrogen-bond donors and the O—H⋯O, O—H⋯S and N—H⋯O hydrogen bonds generate a layer motif.
