Abstract: In the title thiosemicarbazone derivative, C₉H₁₀N₄OS·H₂O, intramolecular N-HN hydrogen bonds result in the formation of two nearly coplanar five- and six-membered rings, which are also almost coplanar with the adjacent phenyl ring. The oxime group has an E configuration and is involved in intermolecular O-HO hydrogen bonding as a donor. In the crystal structure, intramolecular O-HS and N-HN and intermolecular O-HO and N-HS hydrogen bonds generate edge-fused R₂²(8) and R₄¹(11) ring motifs. The hydrogen-bonded motifs are linked to each other to form a three-dimensional supramolecular network.
