We investigate several issues related to the electronic states in the ligand orbital of a given transition-metal salt as, for example, a K₂CuCl₄·2H₂O-type compound. In fact, to get our calculation, we start from an expression for the electronic density of states in a compound of the above type. In addition, various aspects related to superexchange interaction in both the paramagnetic and ferromagnetic cases are discussed and the electronic conduction process in the ligand orbital is studied.
