Crystal structure of chlorfluazuron.

ABSTRACT: The title compound (systematic name: 1-{3,5-di-chloro-4-[3-chloro-5-(tri-fluoro-meth-yl)pyridin-2-yl-oxy]phen-yl}-3-(2,6-difluoro-benzo-yl)urea), C20H9Cl3F5N3O3, is a benzoyl-phenyl-urea insecticide. The dihedral angles between the planes of the central di-chloro-phenyl and the terminal di-fluoro-phenyl and chloro-pyridyl rings are 79.51 (6) and 78.84 6)°, respectively. In the crystal, pairs of N-H⋯O hydrogen bonds link adjacent mol-ecules, forming R 2 (2)(8) inversion dimers. In addition, the dimers are linked by short F⋯Cl [3.1060 (16) Å] and Cl⋯Cl [3.2837 (7) Å] contacts, as well as weak inter-molecular π-π inter-actions [ring centroid separation = 3.6100 (11) and 3.7764 (13) Å], resulting in a two-dimensional architecture parallel to (111).

Crystal structure of Ba5In4Sb6.

Project description:The title compound, penta-barium tetra-indium hexa-anti-mony, was synthesized by an indium-flux reaction and its structure features layers composed of edge-sharing In2Sb6 units.
