You would use bis-, tris-, and tetrakis- if the ligand already contains a prefix. So, for example, Pd[P(C6H5)3]4 is palladium(0) tetrakis(triphenylphosphine). Tetrakis- is used instead of tetra- since tri- is already used in the ligand's name. Hope this helps!

So you use bis-, tris-, and tetrakis- if there are multiple of the same ligand ?
This is an example.
[Co(H2NCH2CH2NH2)3]2(SO4)3
Answer:
tris(ethylenediamine)cobalt(III) sulfate
