title: Crystal structure of cyclo-sulfamuron.
abstract: The title compound (systematic name: 1-{[2-(cyclo-propylcarbon-yl)anilino]sulfon-yl}-3-(4,6-di-meth-oxy-pyrimidin-2-yl)urea), C17H19N5O6S, is a pyrimidinyl-sulfonyl-urea herbicide. The dihedral angles between the mean planes of the central benzene ring and the cyclo-propyl and pyrimidinyl rings are 75.32 (9) and 88.79 (4)°, respectively. The C atoms of the meth-oxy groups lie almost in the plane of the pyrimidine ring [deviations = 0.043 (2) and 0.028 (2) Å] and intra-molecular 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 inter-actions [centroid-centroid distances = 3.6175 (9) and 3.7068 (9) Å] link adjacent mol-ecules, forming a three-dimensional network.
