【 摘 要 】

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 asymmetric unit comprises two independent mol­ecules, A and B, in which the dihedral angles between the pyridinyl and triazinyl ring planes [r.m.s. deviations = 0.0132and 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.
