Although both nitrogen and phosphorous take place in Group VA, in complex formation ammonia acts as sigma-donor while PR3 is both sigma–donor and pi-acceptor. In the light of this explanation, show the sigma and pi interactions in [Co(PR3)6]2+ according to MO theory. What makes PR3 a different ligand than ammonia? Do I need to replace t2g orbitals in my diagram? How can I show PR3 ligands using d orbitals?
