A second triclinic polymorph of azimsulfuron.

ABSTRACT: The title compound, C₁₃H₁₆N₁₀O₅S (systematic name: 1-(4,6-di-meth-oxypyrimidin-2-yl)-3-{[1-methyl-4-(2-methyl-2H-tetra-zol-5-yl)pyrazol-5-yl]sulfonyl}urea), is a second triclinic polymorph of this crystal [for the other, see: Jeon et al., (2015 ▸). Acta Cryst. E71, o470-o471]. There are two mol-ecules, A and B, in the asymmetric unit; the dihedral angles between the pyrazole ring and the tetra-zole and di-meth-oxy-pyrimidine ring planes are 72.84 (10) and 37.24 (14)°, respectively (mol-ecule A) and 84.38 (9) and 26.09 (15)°, respectively (mol-ecule B). Each mol-ecule features an intra-molecular N-H⋯N hydrogen bond. In the crystal, aromatic π-π stacking inter-actions [centroid-centroid separa
