A complex ion has a metal ion at its center with a number other molecules or ions surrounding it.
They are attached to the central ion by coordinate (dative covalent) bonds.
The molecules or ions surrounding the central metal ion are called ligands.
The active lone pairs of electrons in the outer energy shell are used to form coordinate bonds with the metal ion.
