Question

Why do transition metals form large number of complexes?

Answer 1

transition-metal ions form coordination complexes because they have empty valence-shell orbitals that can accept pairs of electrons from a Lewis base. Ligands must therefore be Lewis bases. They must contain at least one pair of nonbonding electrons that can be donated to a metal ion.
