It's not off topic. CCP4BB is for protein crystallography. Discussions
of crystallographic programs are particularly ON TOPIC! But so are
media, viruses, vectors and buffers...
Having said that, you might like to consider the Coot mailing list - you
may get answered faster there. But, Coot questions are welcome here also.

Coot pudding?

Presumably you have merged your molecules?
If you want to display the bond then you need a LINK record in your pdb
file (Coot doesn't make them).
If you want to use the bond in refinement, then you need "Sphere
Refinement". This is discussed in the Coot User Manual.
