CoBr2, or cobalt(II) bromide, is an inorganic compound composed of cobalt and bromine. It typically appears as a reddish-brown solid and is used in various chemical applications, including as a catalyst in organic reactions. CoBr2 is known for its ability to form complexes with other molecules, which can enhance its reactivity. In terms of structure, CoBr2 features a coordination number of six, meaning that each cobalt atom is surrounded by six bromine atoms. This arrangement contributes to its stability and solubility in polar solvents. CoBr2 is also of interest in the field of coordination chemistry, where it serves as a model for studying metal-bromine interactions.
