title: 4-(2-{[4-Amino-6-(4-nitro-benz-yl)-5-oxo-4,5-dihydro-1,2,4-triazin-3-yl]sulfan-yl}acet-yl)-3-phenyl-sydnone.
abstract: In the crystal, C(20)H(15)N(7)O(6)S, the dihedral angle between the oxadiazole and triazine rings is 86.94 (7)°. The oxadiazole ring makes a dihedral angle of 52.96 (8)° with the phenyl ring, while the triazine ring makes a dihedral angle of 82.08 (7)° with the benzene ring. In the structure, mol-ecules are linked by a pair of N-H⋯O hydrogen bonds, forming an inversion dimer. The dimers are further stacked along the a axis via N-H⋯N hydrogen bonds. Weak inter-molecular C-H⋯O inter-actions are also observed.
