The title compound, C(18)H(14)N(6)O(2)S, exists in trans and cis configurations with respect to the two acyclic C=N bonds [bond lengths = 1.2835 (9) and 1.3049 (9) Å]. The 3,6-dihydro-2H-1,3,4-thia-diazine ring adopts a half-boat conformation. The oxadiazol-3-ium ring makes dihedral angles of 53.70 (4) and 60.26 (4)° with the two phenyl rings. In the crystal, mol-ecules are linked via pairs of inter-molecular N-H⋯N hydrogen bonds, generating R(2) (2)(8) ring motifs, and are further linked via in ...[more]
