✦ Synopsis

The title compound, C 10 H 8 FN 5 OÁH 2 O, was synthesized by the reaction of (1H-1,2,4-triazol-3-yl)hydrazine with 4-fluorobenzaldehyde in ethanol. The molecule is almost planar and in the crystal structure screw-related molecules are linked by N-HÁ Á ÁO and N-HÁ Á ÁN hydrogen bonds to form chains along the b axis. The chains are interlinked by the water molecules via O-HÁ Á ÁN hydrogen bonds.
