Ethylene diamine is an example of a              ligand:

${\left[\mathrm{M}{\left({\mathrm{H}}_2\mathrm{O}\right)}_4\right]}^{+2}+4{\mathrm{CH}}_3{\mathrm{NH}}_2\stackrel{{\mathrm{K}}_1}{\to }\mathrm{A}; ∆{\mathrm{G}}_1^0$

${\left[\mathrm{M}{\left({\mathrm{H}}_2\mathrm{O}\right)}_4\right]}^{+2}+2{\mathrm{H}}_2{\mathrm{NCH}}_2{\mathrm{CH}}_2{\mathrm{NH}}_2\stackrel{{\mathrm{K}}_2}{\to }\mathrm{B}; ∆{\mathrm{G}}_2^0$
