Cdbr2

Compound CdBr2 is a binary inorganic compound that consists of one cadmium atom and two bromine atoms. It has a molar mass of 272.22 g/mol and appears as a white crystalline solid at room temperature.

CdBr2 adopts a crystal structure known as the CdCl2-type or layer structure, where each cadmium ion is surrounded by six bromine ions to form an octahedral coordination geometry. The layers are stacked on top of each other in an ABAB... pattern, with weaker Van der Waals forces between the layers holding them together. This results in weak interlayer bonding and the ability of CdBr2 to exfoliate into single-layer sheets.

CdBr2 is sparingly soluble in water, with a solubility of 0.57 g/100 mL at 25 °C. It is soluble in polar organic solvents such as methanol and ethanol. Upon heating, CdBr2 decomposes to produce toxic fumes of cadmium oxide and hydrogen bromide gas.

CdBr2 is used in various applications, including as a precursor for the synthesis of semiconductor materials, in electroplating processes, and in the manufacturing of optical lenses and infrared detectors. However, its use is restricted due to its toxicity and potential environmental hazards.
