I have solved a protein structure using anomalous signal using mercury(II)potassium Iodide(K2HgI4).

I wanted to submit the structure of the protein with mercury(II) potassium iodide to PDB.

I am facing problems while making the ligand (HGI4) . HGI4 is not available in the pdb.

Make Ligand in CCP4 is showing error

I have attached the screenshots for reference.



If it really is tetrahedral you could try the attached (TIM is already taken so you'll have to rename it  - or wwPDB will do it for you).

I desalted it of course. I also updated (hand-edited) the bond distances using the Acedrg Tables reference.

If successful, send us a picture of the post-refinement maps.
