[Wien] how to generate supercell of 14 atoms

[delamora]

Depending on the symmetry you can put 2 cells in a, b or c direction. The direction would be in which the replaced atom is furthest apart.

>From the formula it seems to be tetragonal, so you can put 2x2x1 and replace in cells in the diagonal and you will have after "group" a rotated cell by 45.

Asunto: [Wien] how to generate supercell of 14 atoms

Dear Wein users

I have a unit cell with formula A2BO4 (7 atoms). I need to dope 25% of C at A site (A1.5C0.5BO4). To get required composition I need to generate 14 atoms in supercell. While trying to generate supercell in Wein2K, only possible number of atoms (6, 8, 16, 32, 24, 48 atoms) can be generated.
Q-1 How to generate a supercell having 14 atoms or multiple of it?
Q-2 Using existing possibility to generate a supercell, can I have composition A1.5C0.5BO4?

?Kindly help me.?

?With Regards?
