Crystal structure of fluroxypyr.

ABSTRACT: In the title pyridine herbicide {systematic name: 2-[(4-amino-3,5-di-chloro-6-fluoro-pyridin-2-yl)-oxy]acetic acid}, C₇H₅Cl₂FN₂O₃, the mean plane of the carb-oxy-lic acid substituent and the pyridyl ring plane subtend a dihedral angle of 77.5?(1)°. In the crystal, pairs of O-H?O hydrogen bonds form inversion dimers with R₂²(8) ring motifs. These are extended into chains along [011] by N-H?F hydrogen bonds. In addition, inter-molecular N-H?O hydrogen bonds and weak ?-? inter-actions [ring centroid separation = 3.4602?(9)?Å] connect these chains into a three-dimensional network.
