[QE-users] Incorrect Visualization of Ba₂ZrS₄ Body-Centered Tetragonal Structure in XCrySDen from Quantum ESPRESSO Input

[Asma Khatun]

Dear Quantum ESPRESSO Community,

I am trying to model the Ba₂ZrS₄ compound with a body-centered tetragonal
(bct) structure using Quantum ESPRESSO. However, when I visualize the
structure using XCrySDen from my SCF input file (ba2zrs4.scf.in), the
crystal does not appear as expected. The atomic positions and symmetry seem
incorrect even before running any calculation.
To help identify the issue, I have attached:

a) ba2zrs4.scf.in: My input file used for visualization.

b) unitcell.png:  The structure as visualized in XCrySDen.

Could anyone kindly review my input file and advise if there is any mistake
in the lattice vectors, atomic positions, or crystal symmetry definition?
Any help would be sincerely appreciated.

Thank you very much for your time and support.

Best regards,
