Acta Crystallogr E Crystallogr Commun. 2017 Sep 12;73(Pt 10):1439-1442. doi: 10.1107/S2056989017012737. eCollection 2017 Oct 1.

Abstract

The title compound, {systematic name: 1-[3-({[(4,6-di-meth-oxy-pyrimidin-2-yl)carbamo-yl]amino}-sulfon-yl)pyridin-2-yl]-2-fluoro-propyl 2-meth-oxy-acetate}, C18H22FN5O8S, is used as a herbicide (pyrimidinyl-sulfonyl-urea herbicide). The dihedral angle between the mean planes of the pyridine and pyrimidine rings is 86.90 (7)°. In the crystal, N/C-H⋯O hydrogen bonds, C-H⋯F and C-H⋯π inter-actions link adjacent mol-ecules, forming a chain along [020]. A further two C-H⋯O hydrogen bonds together with weak π-π inter-actions [ring centroid separation = 3.7584 (12) Å] further aggregate the structure into a three-dimensional architecture.

Keywords: crystal structure; flucetosulfuron; herbicides; pyrimidinyl­sulfonyl­urea herbicide.
