How come the hydrogen atoms don show up when I add hydrogens?
A. Remember, X-Seed gets SHELX to do all the dirty work. The “Add Hydrogens” feature of X-Seed only tags the parent atoms for hydrogen atom generation. The next time you run SHELXL-97, the appropriate HFIX commands will be inserted into the INStruction file and SHELX will generate the hydrogen atoms. When you accept the results of the SHELXL run, the hydrogen atoms will be there.
