Hi Marek,
Thanks for the suggestion — I guess I don’t see many metal complexes in Mol2 files so this got overlooked.  I’ve implemented it now and it will be available in the next daily build.

Hello,

it seems that Chimera (1.11.2) has problem to save some bonds in MOL2 format.

If you open attached file "source.mol2" , Chimera reads/show perfectly all
the bonds including those where is "Ru" atom present, but when you save it in MOL2
format in Chimera (see attached file "Chimera_MOL2.mol2"), then all the "Ru-x" bonds are omitted
and naturally if you open this "Chimera MOL2" file in Chimera no "Ru-x" bonds are shown.

Interestingly, if the original MOL2 file "source.mol2" is opened in Chimera and then saved
in PDB format ("Chimera_PDB.pdb"), all bonds are written and so if this PDB file is opened
in Chimera all bonds are visualized.

Would be nice if the perfect bond preservation which works in MOL2->PDB case worked also
in MOL2->MOL2 case.

  Best wishes,

      Marek
