چکیده
The title compound {systematic name: 1-(4,6-di-meth-oxy-pyrimidin-2-yl)-3-[1-methyl-4-(2-methyl-2H-tetra-zol-5-yl)pyrazol-5-ylsulfon-yl]urea}, C13H16N10O5S, is a sulfonyl-urea herbicide. In this compound, the dihedral angles between the planes of the central pyrazole and the terminal di-meth-oxy-pyrimidine and tetra-zole rings are 79.10 (8) and 17.21 (16)°, respectively. In the crystal, N-H⋯O hydrogen bonds link adjacent mol-ecules, forming R 2 (2)(8) inversion dimers. In addition, weak C-H⋯O and C-H⋯N hydrogen bonds and weak π-π inter-actions [ring centroid separation = 3.8255 (12) Å] are present, resulting in a three-dimensional architecture.
