Which of the following ligand(s) is/are ambidentate?

Ambidentate ligand is a type of ligand which can attach to the central metal atom through atoms of two different elements. More specifically ambidentate ligands have more than one donor atom but during coordinate bond formation only one of them attaches itself to the central metal atom.

Examples: ${\mathrm{NOS}}^{\mathrm{\Theta }}$, ${\mathrm{SCN}}^{\ominus }$ and ${\mathrm{NO}}_2^{\ominus }$
