Give examples of ambidentate ligands.

An aqueous solution of $1 \ mol$ of the coordination compound $[Co(NH_3)_5Cl_3]$ gives $3 \ mol$ of ions. If $1 \ mol$ of the same compound reacts with $2 \ mol$ of $AgNO_3$ to produce $2 \ mol$ of $AgCl_{(s)}$,what is the correct formula of the coordination compound?

In the compound lithium tetrahydroaluminate,the ligand is
