Hi Pietro

I use 6.4.1 (the latest one for witch Windows binary are available for download from QE listed WWW).

The whole non functional input follows. If you can check this, it will be very helpful.

Hi

 which version of the code are you using ?



with qe-6.6 using  your parameters I got two positions



  site n.     atom                  positions (alat units)

         1           Zn  tau(   1) = (   0.4873906   2.5406690   1.4472625  )

         2           Zn  tau(   2) = (   0.3343454   0.8468897   0.4736359  )



With alat = 11.5468  a.u.



alat = 11.5468  a.u.



ibrav=-12





hope it helps

greetings  - Pietro
