Cobalt Arsenide is a crystalline solid used as a semiconductor and in photo optic applications. An arsenide, an anion with the charge 3, is a rare mineral group consisting of compounds of one or more metals with arsenic (As). Arsenide anions have no existence in solution since they are extremely basic. These solid salts have very high lattice energies and are toxic due to the inherent ...
