WebExamples for anionic ligands are F –, Cl –, Br –, I –, S 2–, CN –, NCS –, OH –, NH 2– and neutral ligands are NH 3, H 2 O, NO, CO. A ligand is an ion or molecule, which binds to the central metal atom to form a coordination entity or complex compounds. Classification of ligands is on the basis of the number of binding sites ... WebThe last point is most important. Rather than learning or attempting to remember that chloride is a weak-field ligand, ask yourself why. It is a π donor ligand that will split the $\mathrm{t_{2g}}$ orbitals of the central metal in a bonding–antibonding way, lifting the metal’s $\mathrm{t_{2g}}$ orbitals and lowering the energy difference.
