In SCl6, smaller S cannot accomodate six larger Cl– ions.
PH5 does not exist as there is large difference in the energies of s, p and d orbitals of P and hence it does not undergo sp3d hybridisation.
NCl5 does not exist as there is no d-orbital with N.
BF6 3– does not exist as there is no vacant d-orbital in B and hence it cannot exceed its covalency beyond four.
