I realize that I left out a key detail, and had a typo on my last

(despite the fact that I read in the mon_lib.cif file before reading
in the coordinates for the monomer(s) in question).
Les,
When one successfully reads a dictionary cif file (typically
monomer-XXX.cif, if it has come from LIBCHECK via Coot) Coot will tell
you that it has read n bonds from the dictionary - if it doesn't do that
then I worry. Look for "dirty cif?" message in the console.
Are you sure that the three-letter-codes of the PDB coordintes match
that in the cif dictionary?
How, more precisely, did you make you dictionary? I presume this is a
ligand you designed yourself (and not something in the refmac dictionary?).
For the archive:
This was resolved off-air. The PDB file out of sketcher had 2-char atom
names formatted like this: "C2 ", whereas Coot (which tries to match
dictionary atom names with PDB atom names) expects 2-char atom names to
be formatted like this: " C2 ". An alternative solution (not tested)
would be to quote the atom names in the dictionary cif file.
