The six-membered ring fused to the 1,4-thia-zine ring makes dihedral angles of 63.04 (2) and 54.7 (2)° with the mean planes through the five-membered heterocycle and the attached phenyl ring, resp...

In the crystal of the title compound, C(15)H(18)N(2)O(4)S, inversion dimers are formed by inter-molecular N-H⋯N hydrogen bonds and weak C-H⋯O contacts. These dimers stack up along [100] through inversion-related π-π inter-actions between thia-zole rings [centroid-centroid distance = 3.790 (2) Å] and the thia-zole and benzene rings [centroid-centroid distance = 3.845 (2) Å] and C-H⋯π contacts.

In the mol-ecule of the title compound, C(11)H(15)N(5)OS(2), the thia-diazole and triazole rings are not coplanar, the dihedral angle formed by their mean planes being 59.9 (2)°. The exocyclic S atom, and the methyl-ene, carbonyl, tert-butyl and one methyl carbon form an approximately planar zigzag chain, which makes a dihedral angle of 74.6 (1)° with the thia-diazole ring.

In the polymeric title compound, {[Ag(C(8)H(10)N(4)S(4))]ClO(4)·1.5H(2)O}(n), the Ag(I) atom has a slightly distorted trigonal-planar coordination geometry provided by three N-atom donors from the thia-diazole rings of three symmetry-related 2,2'-[butane-1,4-diylbis(sulfanedi-yl)]bis-(1,3,4-thia-diazole) ligands. Centrosymmetrically related Ag(I) atoms are bridged by the N-N fragments of rings,...
