The observed planarity correlates with the presence of bifurcated N-H⋯(O,N) hydrogen bonds. In the crystal, the mol-ecules are connected into supra-molecular double chains via a combination of N-H⋯S (linking the two independent mol-ecules), O-H⋯O and O-H⋯N (linking dimeric aggregates into a supra-molecular chain via hy-droxy-water, water-water and water-pyrazine inter-actions) and O-H⋯S hydrogen bonds (connecting two chains). The chains are further connected by C-H⋯N and C-H⋯S inter-actions.Acta crystallographica.
