31、Red Book II).One of the main changes from the old Red Book is the different organization of material,adopted to improve clarity.Overall,the emphasis on additive nomenclature(generalized from the classical nomenclature of coordination compounds)which was already apparent in the 1990 Red Book,is reinf
