The coordination number of Cs^(+) ion in...

The coordination number of `Cs^(+)` ion in CsCl crystal is ________

A

8, 8

B

4, 4

C

6, 6

D

8, 4

Text Solution

Verified by Experts

The correct Answer is:
A
Each Cs ion is surrounded by 8 `Cl^(-)` ions and each `Cl^(-)` ion is surrounded by 8 `Cs^(+)` ions. CsCl has a bcc type structure. Thus, the structure has 8:8 coordination number.

Define coordination number of a metal ion in an ionic crystal

Define coordination number of a metal ion an ionic crystal.

In a close packed structure, the atoms stack together occupying maximum space and leaving minimum vacant space. The close packing arrangment may be hcp (ABABA….) or ccp (ABCABCA….). In these arrangments, there is one octahedral void and two tetrahedral voids. Depending upon the ratio of size of cation and anion, the ions of one type occupy the voids of other ions. This results in different types of crystalline structures. Predict the coordination number of Cs^(+) ion and structure of CsCl , if radii of Cs^(+) and Cl^(-) ions are 1.69 Å and 1.81 Å respectively.
