My favourite bond prediction server is ... http://www.mrc-lmb.cam.ac.uk/genomes/nci/ However, it looks down for the time being. Here is the reference... http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=168935 It predicts canonical bonds as well as 'non-canonical', but not electrostatic interactions (as far as I know). Predicting quaternary structure is a big field, with many different groups trying many different approaches. I would suggest you ask your question here pdb-l at rcsb.org All the best, Dan.
