In 2022,Kaya, Meltem; Demir, Sevde; Arici, Mursel; Wriedt, Mario; Yesilel, Okan Zafer published an article in Polyhedron. The title of the article was 《Synthesis, characterization, and optical properties of four coordination polymers with 3,5-dicarboxy-1-(4-cyanobenzyl)pyridin-1-ium bromide》.Safety of 4-Cyanobenzyl bromide The author mentioned the following in the article:
Four coordination polymers based on a new 3,5-dicarboxy-1-(4-cyanobenzyl)pyridin-1-ium bromide (H2cbpyBr), formulated as {[Mn(μ-cbpy)2]·2H2O}n (1), {[Co(μ-cbpy)2]·2H2O}n (2), {[Cu(μ-cbpy)2]·H2O}n (3) and {[Zn3(μ-cbpy)6]·6H2O}n (4) were synthesized and characterized by x-ray single-crystal, IR spectroscopy, powder diffraction, and elemental anal. X-ray diffraction anal. revealed that isostructural complexes 1, 2, and 4 displayed 1D structures while complex 3 exhibited 3D coordination polymer with 66-dia topol. In complexes 1, 2, and 4, the adjacent 1D chains were further assembled by π···π and C:N, π interactions into the 3D supramol. framework. Furthermore, optical properties for the compounds were calculated and thermal behaviors of all the complexes were studied at 30-1000°. In the experiment, the researchers used 4-Cyanobenzyl bromide(cas: 17201-43-3Safety of 4-Cyanobenzyl bromide)
4-Cyanobenzyl bromide(cas: 17201-43-3) is a white solid. Its melting point is 113-117°C, and flash point is 125.1°C. It is insoluble in water at 20°C. It is stable under normal temperatures and pressures. It should be stored at 0-5°C.Safety of 4-Cyanobenzyl bromide
