The molecular formula of various hexacoordinate complexes are given as below.
(1) ${CrCl}_{3} \cdot 6 {NH}_{3}$
(2) ${CrCl}_{3}, 5 {NH}_{3}$
(3) ${CrCl}_{3} \cdot 4 {NH}_{3}$
If the number of ${NH}_{3}$ ligands attached to the central metal ion respectively are $6, 5$ and $4,$ then the primary valencies in $(1), (2)$ and $(3)$ respectively are:
