In the title compound, C14H10N6O2S, the dihedral angle between the pyridine and triazole rings is 3.21 (10)°. The molecule is significantly twisted about the Nt—Nb (t = triazole and b = benzylidene) bond [C—Nt—Nb=C = 151.64 (17)°]. In the crystal, molecules are linked by weak N—H⋯N hydrogen bonds, generating C(8) chains propagating in [10].

The title complex was prepared according to the literature procedures (Wang et al. (2010)). Colourless prisms were recrystallised from dimethylformamide solution at room temperature.
All the H atoms were positioned geometrically (C—H = 0.93–0.97 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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 > σ(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. |
