The title compound, C10H11N5O {systematic name: 6-methyl-4-[(E)-(pyridin-3-ylmethylidene)amino]-4,5-dihydro-1,2,4-triazin-3(2H)-one}, C10H11N5O, is used as an antifeedant in pest control. The comprises two independent molecules, A and B, in which the dihedral angles between the pyridinyl and triazinyl ring planes [r.m.s. deviations = 0.0132 and 0.0255 ] are 11.60 (6) and 18.06 (4)°, respectively. In the crystal, N—H⋯O, N—H⋯N, C—H⋯N and C—H⋯O hydrogen bonds, together with weak π–π interactions [ring-centroid separations = 3.5456 (9) and 3.9142 (9) Å], link the pyridinyl and triazinyl rings of A molecules, generating a three-dimensional network.
Keywords: crystal structure; pymetrozine; triazinone; insecticide; antifeedant; hydrogen bonding; π–π interactions.

The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH2Cl2 gave single crystals suitable for X-ray analysis.
All H-atoms were positioned geometrically and refined using a riding model with d(N—H) = 0.88 Å, Uiso = 1.2Ueq(C) for the amine group, d(C—H) = 0.98 Å, Uiso = 1.2Ueq(C) for the methyl group, d(C—H) = 0.99 Å, Uiso = 1.2Ueq(C) for methylene C—H and d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for aromatic H atoms

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. |

Pymetrozine: 4,5-dihydro-6-methyl-4-[(E)-(3-pyridinylmethylene)amino]-1,2,4-triazin-3(2H)-one, is an insecticide for the control of sucking insects, including the brown planthopper, Nilaparvata lugens, one of the most serious pests to affect rice crops (He et al., 2011). Its crystal structure is reported herein. In the title compound (Fig. 1), the asymmetric unit comprises two independent molecules (A and B) and the dihedral angles between the pyridinyl and triazinyl ring planes are 11.60 (6) and 18.06 (4)° for A and B, respectively. All bond lengths and bond angles are normal and comparable to those observed in a similar crystal structure (Wang et al., 2012).
The crystal structure, Fig. 2, is stabilized by intermolecular N—H···O, N—H···N, C—H···N and C—H···O hydrogen bonds (Table 1). In addition, weak intermolecular π···π interactions between the pyridinyl and triazinyl rings link adjacent A molecules [Cg1···Cg2i, 3.5456 (9) Å and Cg1···Cg2ii, 3.9142 (9) Å] symmetry codes: (i) = x + 1/2, -y + 1/2, z + 1/2, (ii) = x + 1, y, z; Cg1 and Cg2 are the centroids of the N1···C5 and N3···C9 rings, respectively]. The π···π interactions together with C1–H1···N5 hydrogen bonds generate sheets of A molecules in the ac plane. All of these contacts combine to generate a three dimensional network, Fig. 2.
