Abstract

In the title triazolothia-diazin compound, C(24)H(24)N(6)O(3)S (systematic name: 4-{3-[(2-isopropyl-5-methyl-phen-oxy)meth-yl]-7H-1,2,4-triazolo[3,4-b][1,3,4]thia-diazin-6-yl}-3-(4-methyl-phen-yl)-1,2,3-oxadiazol-3-ium-5-olate), an intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The two terminal methyl groups of the isopropyl unit are disordered over two sets of positions in a 0.715 (4):0.285 (4) ratio. The mean planes formed through the major and minor disordered isopropyl units are inclined at inter-planar angles of 73.1 (4) and 86.6 (8)°, respectively, with the attached phenyl ring. The 3,6-dihydro-1,3,4-thia-diazine ring adopts a twist-boat conformation. The inter-planar angle formed between 1,2,3-oxadiazole and 1,2,4-triazole rings is 18.80 (11)°. In the crystal, neighbouring mol-ecules are linked into sheets lying parallel to the bc plane by C-H⋯N hydrogen bonds. Weak inter-molecular π-π inter-actions [centroid-centroid distances = 3.2935 (11) and 3.5590 (12) Å] further stabilize the crystal structure.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1)K.
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
