Hi again,<div><br></div><div>So the problem has been solved by adding a bond line into the CIF that explicitely tells phenix that the "bond" should be 4 angstroms instead of 2.1. But I don't understand why Phenix would somehow see that these atoms should be bonded together. This is a phenyl immidazole ligand with two nitrogens, one of which is about 1.9 angstroms from the iron (a real coordination). The other is about 4 angstroms. Why does phenix seem to want to assign a bond between the nitrogen further away?</div>

I have a ligand bound to a heme and I have supplied a CIF for phenix in refinement. I did not include all atoms just, those close to the iron. Unfortunately, I am getting very large reported bond deviations for other atoms. For example I get:</div>

N3 and FE are not bonded and not expected to be close to one another. it is not supported by the structure. I suspect that this is causing my overall bonds deviations to be ~0.03 even if I greatly reduce the weight of wxc.</div>
