पर्याय

• $$[\mathrm{Ni}(\mathrm{NH}{\phantom{A}}_3){\phantom{A}}_4(\mathrm{H}{\phantom{A}}_2\mathrm{O}){\phantom{A}}_2]{\phantom{A}}^{2+}$$

• $$[\mathrm{Pt}(\mathrm{NH}{\phantom{A}}_3){\phantom{A}}_2\mathrm{Cl}{\phantom{A}}_2]$$

• $$[\mathrm{Co}(\mathrm{NH}{\phantom{A}}_3){\phantom{A}}_5\mathrm{SO}{\phantom{A}}_4]\mathrm{Cl}$$

• $$[\mathrm{FeCl}{\phantom{A}}_6]{\phantom{A}}^{3-}$$

Answer 1

$$[\mathrm{FeCl}{\phantom{A}}_6]{\phantom{A}}^{3-}$$
