• If one type of ligand is comes more times means it can be named with prefix: $\left(1\right)$ mono- (usually omitted), $\left(2\right)$ di-, $\left(3\right)$ tri-, $\left(4\right)$ tetra flowed by its name.
• Metal in the anionic complex is named as –ate in its suffix and negative ligands are named as –ato in its suffix.
