CsCl has ______ Coordination.
Do you remember the structure of CsCl compound?
If not, Let’s revise it together.
It has body-centered cubic (bcc) arrangement.
Each Cs⊕ ion is surrounded by eight Cl⊝ ions and each Cl⊝ ion is surrounded by eight Cs⊕ ions, i.e., this structure has 8: 8 coordination.
A unit cell of CsCl consists of only one unit of CsCl, i.e., one Cs⊕ ion and one Cl⊝ ion (because each ion present at the corner is shared by eight unit cells) [The ratio rCs⊕rCl⊝ = 0.93 which is greater than expected for exact fitting (0.732)].
So, you got it right.
It has 8:8 coordination.
