Abstract:
In the title compound, C(11)H(15)ClN(6)O(4)S, which belongs to the neonicotinoid class of insecticidally active heterocyclic compounds, the six-membered triazine ring adopts an opened envolope conformation. The planar nitro imine group [dihedral angle between nitro and imine groups = 1.07 (7)°] and the thia-zole ring are oriented at a dihedral angle of 69.62 (8)°. A classical intra-molecular N-H⋯O hydrogen bond is found in the mol-ecular structure. Moreover, one classical inter-molecular N-H⋯N and four non-classical C-H⋯O and C-H⋯N hydrogen bonds are also present in the crystal structure. Besides inter-molecular hydrogen bonds, the Cl atom forms an inter-molecular short contact [3.020 (2) Å] with one of the nitro O atoms.
