Bis-, Tris-, Tetrakis-

When do we say bis instead of bi when naming coordination compounds?

Bis is used instead of bi when there are two chelating ligands. For example if there are two ethylenediamine ligands (bidentate and chelating) then you would say bis(ethylenediamine). If there are three chelating ligands it will be tris and if there are four it will be tetrakis.
