In `A^(+)B^(-)` ionic compound radii of `A^(=) and B^(-)` ions are `180 "pm "` and `187` pm respectively .The crystal structure of this compound will be

A

`NaCl` type

B

`CaCl` type

C

`ZnS` type

D

Similar to diamond

Text Solution

Verified by Experts

The correct Answer is:
B
`r_(+) // r_(-) = (180)/(187) = 0.962 `which lies in the range of `0.732 - 1.000` hence coordination number `= 8 `i.e. the structure is `CaCI` type
