My question is: Since I am already using the constraints, therefore somewhat imposing "my solution" on the structure, can I add more complexity to the refinement, using the results of ab initio calculations, and say that this is real? As you probably know already, too much is too much... "Too m

Dear Rietvelders, I am working on a structure of a ferric sulfate, with triclinic symmetry and 50 atoms in the unit cell. We have both X-ray synchrotron and neutron data. At the moment, I am using constraints to keep the O-H bond distances and H-O-H angles within reasonable range. One of the m
