چکیده
In the title compound, C(9)H(10)N(4)O(2)·H(2)O, the oxime unit has an E configuration, and an intra-molecular N-H⋯N hydrogen bond results in the formation of a planar five-membered ring, which is oriented with respect to the aromatic ring at a dihedral angle of 74.82 (17)°. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules and R(2) (2)(8) ring motifs are apparent.

In the title thio-semicarbazone derivative, C(9)H(10)N(4)OS·H(2)O, intra-molecular N-H⋯N 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 inter-molecular O-H⋯O hydrogen bonding as a donor. In the crystal structure, intra-molecular O-H...
