organic compounds
The title compound, C29H26N2OP, containing four planar ring systems, exists in the Z form. The short C
O [2.711 (3) Å] and CN [2.961 (3) and 2.997 (3) Å] intramolecular contacts may indicate the presence of weak intramolecular hydrogen bonds.

The title compound, C18H16N2OS, crystallizes in a triclinic unit cell with two independent molecules in the asymmetric unit. Intermolecular N—HS, C—HO and C—HS hydrogen bonds link the molecules into ribbons, which form stacks with short intra- and intermolecular SC [3.385 (5) Å] and CO′ [3.162 (5) Å] contacts.

organic compounds
In the title compound, C17H14N4OS, the central heterocyclic system formed by the five-membered triazole and thiadiazole rings is planar. The bond lengths within the system indicate some degree of delocalization.
organic compounds
In the title compound, C6H6N2O4, the planar carboxyl group makes a dihedral angle of 74.61 (2)° with the uracil plane. In the crystal structure, intermolecular N—HO and O—HO hydrogen bonds link the molecules into a three-dimensional network.
