The coordination number of ions in ionic solids is decided by the

Assertion : A simplified coordination number ratio for ions of any ionic crystal is inverse of molar ratio. Reason : Coordination number ratio of cation to anion in CaF_(2) (fluorite structure) is 8 : 4.

The coordination number of AlCl_(3) in their solid, solid liquid and gaseous state is respectively :
