What are pi-donors ligands give the examples?
Ligands such as OR−, F−, and Cl− are π donors as a result of the lone pairs that are left after one lone pair has formed the M−L σ bond. Instead of stabilizing the dπ electrons of a d6 ion as does a π acceptor, these electrons are now destabilized by what is effectively a repulsion between two filled orbitals.
