In 2022,Abid Derbel, Marwa; Nasr, Samia; Naili, Houcine; Rekik, Walid published an article in Inorganic Chemistry Communications. The title of the article was 《Thermal behavior and optical properties of a new dimeric 1D mixed halide hybrid material [CuBrCl(C2H8N2)]》.Synthetic Route of Br2Cu The author mentioned the following in the article:
A new organic-inorganic Cu-based hybrid material containing ethylenediamine as organic part and mixed bromide/chloride as halide ions was synthesized and crystallog. characterized. At room temperature, this new compound adopts the monoclinic symmetry (space group P21/m) and presents the following unit-cell parameters: a 6.927(3), b 5.884(3), c 8.399(4) Å, β 94.856(13)° and Z = 2. The 1-dimensional structure of the title compound consists of infinite dimeric chains running along the crystallog. b axis. These chains are constructed from dimeric units [Cu2Br2Cl2(C2H8N2)2] linked together by sharing (Br/Cl) atoms. N-H… Br/Cl H bonds guarantee the connection between the dimeric chains and the cohesion of the structure. The TGA shows that this new hybrid material decomposes in two stages giving rise to the Cu oxide as final residue. The UV-visible absorption shows that the new complex undergoes three optical absorption bands at 238, 317 and 686 nm, resp. From the gap energy value of 2.92 eV the new mixed halide compound is a semiconductor material. The results came from multiple reactions, including the reaction of Cupric bromide(cas: 7789-45-9Synthetic Route of Br2Cu)
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.Synthetic Route of Br2Cu
