Crystal structure of cyclo-sulfamuron.

Abstract

The title compound (systematic name: 1-{[2-(cyclo­propylcarbon­yl)anilino]sulfon­yl}-3-(4,6-di­meth­oxy­pyrimidin-2-yl)urea), C17H19N5O6S, is a pyrimidinyl­sulfonyl­urea herbicide. The dihedral angles between the mean planes of the central benzene ring and the cyclo­propyl and pyrimidinyl rings are 75.32 (9) and 88.79 (4)°, respectively. The C atoms of the meth­oxy groups lie almost in the plane of the pyrimidine ring [deviations = 0.043 (2) and 0.028 (2) Å] and intra­molecular N—H⋯N, N—H⋯O and C—H⋯O hydrogen bonds all close S(6) rings. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds and weak π–π inter­actions [centroid–centroid distances = 3.6175 (9) and 3.7068 (9) Å] link adjacent mol­ecules, forming a three-dimensional network.
