Atoms A, B, C and D are present at corners, face centres, body centres and edge centres and respectively in a cubic unit cell. Find the formula of compound.

Text Solution

Verified by Experts

Contribution by atoms A = `8xx1//8=1`
Contribution by atoms B = `6xx1//2=3`
Contribution by atoms C = `1xx1=1`
Contribution by atoms D = `12xx1//4=3`
`A:B:C:D=1:3:1:3`
Formula of compound = `AB_(3)CD_(3)`.
