Column – I : Formula with ratio of coordination number of cation to anion packing for the given closest 3D packing of anions with anion and anion are in contact
Column – II : Total number of voids of definite shape occupied per unit cell.
 

Column–I		Column–II
A)	$M{X}_2[6:3]$ (fcc)	P)	Half tetrahedral voids are occupied.
B)	$MX[4:4]$ (hcp)	Q)	one third octahedral voids are occupied
C)	$M_2{X}_3[6:4]$ (hcp)	R)	Half octahedral voids are occupied
D)	$M{X}_3[6:2]$ (hcp)	S)	Two thirds octahedral voids are occupied
		T)	Size of the cation can be 0.414 times that of anion
