[phenixbb] Special position ambiguity

[R Sarath]

Hi,
I have to place two carbon atoms (C3 and C6 - in para positions) of a cyclohexane ring from a ligand in special positions (I4122 space-group), with C6' from the symmetry generated molecule overlapping on C3 of the ligand. Can someone please suggest me a way to do so. I tried changing the occupancies of C3 and C6 to 0.5. After refinement, I observe that they don't overlap but instead spoil the fitting of neighbouring atoms of the ligand.
Thanks in advance,
Regards,Sarath
