naming differences

Postby sarahtang4B » Tue Dec 04, 2018 9:34 pm

is naming a compound pentaaquathiocyanato the same as pentaaquathiocyano?

also the book uses chlorido instead of chloro... are these two ligands the same?

not sure about the first one, but in one of the review sessions the TA said that chlorido and chloro meant the same thing.

When do we use bis-, tris- etc. vs di- tri-, etc?

I don't believe your first example would be the same compound, as pentaaquathiocyano would be pentaaquathiocyanido.

On Dr. Lavelle's website there is a link to a pdf ("Naming Coordination Compounds") showing a chart with the different names, one being the name (Ex: chloro) and the other being the new IUPAC name (ex: chlorido). It states that either name will be accepted.

You use bis-, tris-, tetrakis-, pentakis-, etc when the name of the ligand already has a di-, tri-, tetra- inside of it. For example, ethylenediamine already has di inside of the name, so you would say bisethylenediamine, rather than diethylenediamine if there is two of them present in the compound. Another instance you would use bis-, tris-, tetrakis-, is when the ligand is polydentate (it binds to the TM at more than one site).

The difference between chloro and chlorido is that one is the new accepted suffix. Both do mean technically the same thing, its just one is more recent than the other.

I am not sure about the first name that you wrote, but the following two are both accepted and are interchangeable. One is just by older coordination compound naming regulations and the other is not.
