Crystal structure of azimsulfuron

Abstract

The title compound {systematic name: 1-(4,6-dimethoxypyrimidin-2-yl)-3-[1-methyl-4-(2-methyl-2H-tetrazol-5-yl)pyrazol-5-ylsulfonyl]urea}, C13H16N10O5S, is a sulfonylurea herbicide. In this compound, the dihedral angles between the planes of the central pyrazole and the terminal dimethoxypyrimidine and tetrazole rings are 79.10 (8) and 17.21 (16)°, respectively. In the crystal, N—H...O hydrogen bonds link adjacent molecules, formingR22(8) inversion dimers. In addition, weak C—H...O and C—H...N hydrogen bonds and weak π–π interactions [ring centroid separation = 3.8255 (12) Å] are present, resulting in a three-dimensional architecture.
