I have a ligand with two phenyl rings where 2Fo and difference density clearly shows some torsion angle between the two rings.  However, no matter how many times I tilt one ring refinement always makes them coplanar.  Is there an option that I can use in phenix.refine to prevent the co-planarity or how do people typically handle this situation?

Thanks for the help.

All the best,

-Jeff
