Crystal structure of azimsulfuron

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}, C(13)H(16)N(10)O(5)S, 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, forming R (2) (2)(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.
