title: 4-[2-(2-Benzyl-idene-hydrazin-ylidene)-3,6-dihydro-2H-1,3,4-thia-diazin-5-yl]-3-(4-meth-oxy-phen-yl)-sydnone.
abstract: In the title compound, C(19)H(16)N(6)O(3)S, the 3,6-dihydro-1,3,4-thia-diazine ring adopts a twist-boat conformation. The dihedral angle between the meth-oxy-substituted benzene ring and the oxadiazole ring is 71.91 (7)°. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers via pairs of inter-molecular N-H⋯N hydrogen bonds, generating R(2) (2)(8) ring motifs. There is an intra-molecular C-H⋯O hydrogen bond which generates an S(6) ring motif.
