Abstract
A new copper(II) complex [Cu(3,5,6-tcpa)(2,2′-bipy)Cl] (1) has been obtained through the one-pot hydrothermal reaction of copper chloride dihydrate with triclopyr (systematic name 2-((3,5,6-trichloropyridin-2-yl)oxy)acetic acid, abbreviation 3,5,6-Htcpa) and 2,2′-bipyridine (2,2′-bipy) coligands. 1 has crystallized in triclinic crystal system, P

space group. The central copper(II) ion displayed a distorted square–pyramidal geometry and was connected by one chlorido co-ligand (Clˉ), one 3,5,6-tcpa anionic chelator and one chelating 2,2’-bipy ligand to afford a mononuclear structure. 1 is further extended into a 3D network by the non-covalent interactions of H⋯Cl, H⋯O hydrogen bonds, aromatic π⋯π stacking together with Cl⋯Cl halogen bond interactions. The co-crystallization process, the crystal structure of 1 as well as the Hirshfeld surface analysis for 1 have been analyzed and described. In addition, the flexible conformation of phenoxy methylene group among 1, triclopyr acid and its previously reported co-crystallized compound also have been carefully compared and discussed.

Abstract
Abstract
Triclopyr ethyl ester (1) has been co-synthesized through one-pot solvothermal reaction and the crystal structure has been determined by single crystal X-ray structure analysis. The compound C18H16Cl6N2O6 crystallizes in the monoclinic crystal system, P21/c space group with unit-cell parameters: a = 4.9615(2) Å, b = 30.9297(14) Å, c = 15.9155(10) Å, β = 91.466(4)° and Z = 4. Each unit cell is composed of two discrete, similar but reversely arranged triclopyr ethyl ester organic molecules. In the 3D packing plot, 1 is further assembled into a network structure via rich Cl⋯Cl halogen bond interactions. In addition, the crystal structure, the flexible conformation of phenoxy methylene group of 1 has been carefully compared and discussed with those of triclopyr acid.

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 π-π inter-actions [ring centroid separation = 3.4602 (9) Å] connect these chains into a three-dimensional network.
