Transition metal form complexes due to availability of vacant d-orbitals so they can form complex with ligands. These ligands have vacant Π orbitals. The transition metals form Π complexes because they have t2g orbitals of correct symmetry which allows them to overlap with the vacant Π orbitals of these ligands, forming Π bonds. This bonding is known as back bonding. Hence, the presence of d-orbitals of proper symmetry in transition metals allows the formation of p complexes
