Dear Gordon,
thank you for your reply.
I tried to use the space group P1,
but the resulting local structure around the absorber atoms
is completely different from that expected.

HI Andrea,
My suggestion, if you know where all the atoms are in the unit cell, is to
use
space group P1. It may be tedious and brute force in nature, but you won't
have
to worry about origin choices or non-standard space groups. You will still
know
which atoms are equivalent and can pick an appropriate one as your target
atom.
regards,
Robert
