If the value of ionic radius ratio `((r_(c ))/(r_(a)))` is `0.52` in an ionic compound , the geometrical of ions in crystal is

A

planar

B

pyramidal

C

Tetrahedral

D

octahedral

Text Solution

Verified by Experts

The correct Answer is:
D
The value of ionic radius ratio is 0.52 which is in between `0.414 - 0.732`, then the geometrical arrangement of ions crystal is octahedral.
