Naming those Coordination Compounds: 1. Is my complex ion a cation or an anion? Cations are always named first, then anions. 2. What ligands are involved? In the name you list ligands in alphabetical order, ignoring prefixes. In the formula anionic ligands come before neutral ones. You need to memorize the following: NH 3 ammine H 2 O aqua Cl - chloro (all halogens end in “o”) OH - hydroxo CN - cyano NO 2 - nitrito-N or nitrito-O (depends on ligand atom used) H 2 NCH 2 CH 2 NH 2 = ethylenediamine or “en” You’ll be given “en” and the others from Table 22.4 as needed.

Unformatted text preview: mono, di, etc. If the ligand name already has a Greek prefix in it what do I do? Then you use bis for 2 and tris for 3. 4. What about the metal ion? If the complex ion is (+) just use the metal name. If the complex ion is (-) add the ending ate to the metal name. Some use Latin-based names ( see Table 22.5) 5. How do I finish this? For the complex ion : you list the ligands first, then the metal ion followed by its oxidation state given in Roman numerals and placed in parentheses. Finally, give the counter-ion name and remember that (+) ions come first, then (-) ions....
