This work describes a homometallic spin-1/2 tetrabromocuprate adopting a bilayer structure. Magnetic-susceptibility measurements show a broad maximum centered near 70 K, with fits to this data using a Heisenberg model consistent with strong antiferromagnetic coupling between neighboring copper atoms in different layers of the bilayer. There are further weak intralayer ferromagnetic interactions between copper cations in neighboring dimers. First-principles calculations are consistent with this, but suggest there is only significant magnetic coupling within one direction of a layer; this would suggest the presence of a spin ladder within the bilayer with antiferromagnetic rung and weaker ferromagnetic rail couplings. In the experiment, the researchers used Cupric bromide(cas: 7789-45-9Reference of Cupric bromide)
Some reported applications of Cupric bromide(cas: 7789-45-9) are: catalyst in cross coupling reactions; co-catalyst in Sonogashira coupling; lewis acid in enantioselective addition of alkynes.Reference of Cupric bromide
