Bosch, Eric; Bowling, Nathan P.; Oburn, Shalisa M. published their research in Acta Crystallographica, Section C: Structural Chemistry in 2021. The article was titled 《Conformational control through co-operative nonconventional C-H···N hydrogen bonds》.Safety of 2,6-Dibromopyridine The article contains the following contents:
We report the design, synthesis, and crystal structure of a conjugated aryleneethynyl mol., 2-(2-{4,5-dimethoxy-2-[2-(2,3,4-trifluorophenyl)ethynyl]phenyl}ethynyl)-6-[2-(pyridin-2-yl)ethynyl]pyridine, C30H17F3N2O2, that adopts a planar rhombus conformation in the solid state. The mol. crystallizes in the space group P [inline formula omitted] , with Z = 2, and features two intramol. sp2-C-H···N hydrogen bonds that co-operatively hold the arylethynyl mol. in a rhombus conformation. The H atoms are activated towards hydrogen bonding since they are situated on a trifluorophenyl ring and the H···N distances are 2.470 (16) and 2.646 (16) Å, with C-H···N angles of 161.7 (2) and 164.7 (2)°, resp. Mol. electrostatic potential calculations support the formation of C-H···N hydrogen bonds to the trifluorophenyl moiety. Hirshfeld surface anal. identifies a self-complementary C-H···O dimeric interaction between adjacent 1,2-dimethoxybenzene segments that is shown to be common in structures containing that moiety.

2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Safety of 2,6-Dibromopyridine
