Nomenclature of Coordination Compounds • Anionic ligands end in “o”; • neutral ligands are not changed. The complex cation chemical formula follows traditional rules for naming ionic compounds with the cation listed first. Nomenclature is important in Coordination Chemistry because of the need to have an unambiguous method of describing formulas and writing systematic names, particularly when dealing with isomers. So if we name the compound it comes to be potassium tetrachloridopalladium(II) but in the answer it is tetrachloridopalladate(II). Terms. Nomenclature of Complexes: Positive ion is named first followed by negative ion. Naming coordination compounds involves a set of rules which includes the oxidation number of the central ion and the chemical composition of the ligand, focusing on the anionic and cationic properties of the molecule. Overall, the emphasis on additive nomenclature (generalized from the classical nomenclature of coordination compounds), which was already apparent in Red Book I, is reinforced here. Coordination compounds contain an ion and an array of ligands. Nomenclature of Coordination Compounds The general rules for naming the coordination compounds and writing their formulae have been set by IUPAC to avoid any ambiguity.
