Dear People,

I know I can double the cell size by setting for example the first element of the rotation matrix P to 2, but how can I create a supercell where the "newly added cell" has another direction than the "prototype" unit cell?

Is there a possibility to double the unit cell and rotate the new part afterward?

Thanks a lot for your help.

Thank you for your answer.

I do not want to build the whole cell by myself. I have a vesta-file of a unit cell.
I thought I can to stuff like
"New Structure" -> add my original unit cell
"Phase" -> impot the same unit cell again, shift it, rotate it 90° and merge the two cells to a supercell and delete the duplicate atoms.

But it does not really work, I thought there must be a more easy way, than building the whole supercell by my own.

could you do up to importing and rotating, etc.?
and then presume, once you delete the atoms, you could not save them or what?

Actually I could rotate and shift it and I also could save it. But somehow not as a supercell.
I cannot understand how I get the whole list of atom positions. If I export the file i just get the same file as I would get if I export the normal unit cell.

I think I should do a further step to transform the two unit cells into a supercell to get the correct cif file.
