Naming coordination compounds uses a systematic set of rules known as IUPAC, and one important portion of this naming system is the naming of ligands. Now here we're going to say ligands themselves can either be anions or neutral molecules. Remember, we've said before that there are such things as cationic ligands, but we're not going to cover those types of ligands within this general chemistry course. So for right now ligands can either be negatively charged or neutral.
Now if we take a look here on our amniotic or negatively charged ligand side, so for example here bromide ion, its ligand name is bromo oxide is O2-. In terms of its ligand name, it's Oxo. Hydroxide becomes hydroxyl, cyanide becomes cyano. So we can see a kind of theme being formed where we have this O ending of the negatively charged ligand. Azide ion is N3-, 1. Here it would be called izodo and then Nitro is nitrate, Nitrate is Nitro, oxalate anion is oxalado and then carbonate is carbonado.
For our neutral side, here we have the ligand name already. We just have to determine what the formula will be for our login. Aqua is water, so H2O MEME is the ammonia molecule, Carbonyl is Co carbon monoxide. We have nitrosol, which is NO, and then finally we have ethylene diamine. Here. Realize that we have this numerical prefix within it. We'll see how that plays a role in our naming of these different types of ligand structures. Ethylenediamine is just EN for short, so these are the most important and most commonly used negatively charged ligands and neutral ones.
