Suffixes

[veneziaramirez 3I]

What suffixes should we memorize? I understand if one of the ligands has a negative charge of one then -ate is added to the metal, but if it has a negative charge of 2, no suffix is added as demonstrated in 17.29 d)?

[Qining Jin 1F]

The textbook says that "If the complex has an overall negative charge (an anionic complex), the suffix -ate is added to the stem of the metal’s name," so it does not matter if the ligand has a negative charge or not. Because 17.29d has an overall positive charge, no suffix is added to the metal

You should also know the suffixes for polyatomic ions. For example ions at end in -ate, like sulfate, the ending in the coordination compound should be -ato. sulfate --> sulfato. For ions ending in -ite, like nitrite, the ending will be changed to -ito. nitrite --> nitrito.
Another one you should know is -ide to -ido. chloride --> chlorido.
With these basic suffix rules and the need-to-know/exceptions listed in the chart it should be fairly easy to name coordination complexes

[Clarissa Molina 1D]

For prefixes, in what cases would bis- tris- and tetrakis- be used?

[Andrea ORiordan 1L]

You use bis, tris, tetrakis, etc, if the ligand already contains a greek prefix (eg. ethyleneDIamine) or if it is polydentate (eg. oxalate).
