It looks like you're trying to calculate the cone angle of the FPS ligands that are coordinating the Mg ions. You would have to do this one ligand at a time by:
1. selecting one of the FPS ligands
2. clicking the 'set ligand to current selection' button on the tool
3. selecting an Mg atom
4. clicking 'calculate cone angle for ligand on selected center'.
I've tried this out for the /A:301 FPS ligand, and I got a strangely small result of 150 degrees. It seems to either ignore the bridge or the aliphatic chain. I'll take a closer look at that; it might be a bug. I'd suggest trying the 'exact' cone angle if you want to stick with cone angles. That gave me a larger 180 degrees for the same Mg, and it also works for ligands of any denticity.
For a ligand this long, I think buried volume might be a better metric at gauging how accessible those Mg atoms are. The long aliphatic tail, which is far from the coordination site, might be inflating the size of the ligand. Buried volume only looks within a few angstroms of the center. The procedure for calculating %Vbur is roughly the same, but it doesn't matter of something is coordinating or not. With the "Buried Volume" tool open, you could
1. select everything except solvent and Mg (sel ~:HOH & ~Mg), or just the FPS ligands if you prefer
2. click 'set ligand to current selection'
3. make sure 'use centroid of centers' is unchecked
4. select Mg atoms (sel Mg)
5. click 'calculate % buried volume for selected centers'
I get around 50-70% buried volume around each of the Mg atoms when I do this. You could play around with the settings, but the defaults should be pretty much standard. You can also create a visualization of either the buried or free volume around an Mg by going over to the "volume cutout" tab of the tool and choosing one of those to display.
Best,
Tony

I've looked into it, and the 150 degree cone angle is consistent with the Tolman method. Or maybe it's more accurate to say that diphosphate ligands are not handled sensibly, as Tolman was only considering mono- and diphosphine ligands. In the Tolman algorithm, you look at the angle of each substituent/fragment coming off of the chelating atom. For this diphosphate ligand, oxygen atoms are coordinating the metal. The only other thing bonded to these O atoms are the phosphorus atoms. Because the phosphorus atoms are part of the path connecting the coordinating oxygens, Tolman's method says to use the L-M-L angle. Thus, the Tolman cone angle is 150 degrees - double the L-M-L angle.
Basically, I don't see any bugs in the calculation of Tolman cone angles or the tool. Please try using the method outlined in my last comment, with only one Mg atom selected when clicking the "calculate cone angle for ligand on selected center" button. There is also a tutorial for this tool. On the ChimeraX menu, go to Help -> SEQCROW Tutorials -> Calculating Ligand Cone Angles.
Best,
Tony
