The central metal ion in the complex makes available a number of empty orbitals for the formation of co-ordinate bonds with suitable ligands. The inner d-orbitals or outer d-orbitals are involved. The empty hybrid orbitals of metal ion overlap with the filled orbitals of ligand to from metal ligand co-ordinate bonds. For co-ordination number 6 octahedral geometry and `sp^(3),d^(2)ord^(2)sp^(2)` hybridisation involved and for cordiantion number 4 tetrahedral geometry, square planar geometry and `sp^(3).dsp^(2)` hybridisation involved.
