In the structure of the the title compound, C10H8N6O, the triazole and oxadiazole rings are almost coplanar. The oxadiazole ring participates in intermolecular N—H
N hydrogen bonds, forming an infinite network in the ac plane. π–π stacking between parallel oxadiazole rings contributes to the stabilization of the crystal packing.

The tridentate Schiff base ligand 2,4-dihydroxyacetophenone salicylhydrazide, derived from the condensation of 2,4-dihydroxyacetophenone and salicylhydrazide, in the presence of pyridine and N,N′-dimethylformamide, forms a dinuclear distorted square-pyramidal Zn complex with Zn(OAc)2·2H2O, viz. [Zn2(C15H12N2O4)2(C5H5N)2]·2C3H7NO. The complex is centrosymmetric and the two Zn atoms are bridged by two phenolate O atoms.

The title compound, C9H11N4O2S, consisting of a pyrimidine ring and a thiourea carboxylic acid methyl ester, possesses mirror symmetry and an intramolecular N—HN hydrogen bond. In the crystal structure, N—HS hydrogen bonds link symmetry-related molecules to form dimers, which in turn are linked by a C—HO hydogen bond to form a two-dimensional planar structure.
