bn (1,2-diaminobutane): This is a bidentate (T) ligand with two N-donor atoms (P) and a chiral center (R) at the second carbon atom.

$Gl{y}^{-1}$ (Glycinato): This is an unsymmetrical bidentate (T) ligand containing both N (P) and O (Q) donor atoms.

en (ethylenediamine): This is a symmetrical bidentate (T) ligand that uses two N-donor atoms (P) to coordinate.

$EDT{A}^{4-}$: This is a polydentate, specifically hexadentate (S), ligand with two N (P) and four O (Q) donor atoms.

Conclusion: Matching these properties ($1\to PRT,2\to PQT,3\to PT,4\to PQS$)
