('binary' encoding is not supported, stored as-is) Also, when defining these residues. When in the defined residue the
carbon atom does not have any electronwithdrawing groups attached, but in
the bonded state it does, how do you define the hydrogens, as h1 or hc?

I built some polymers with a tetrahedral core where I needed to
make a series of connections to the central unit. What I did
was to define a tail, connect a side-chain to it, then redefine
another tail, connect to that, etc. I believe that you can define
a tail as many times as you want, but it will be set to whatever
the last atom you set it to. As already suggested, 'desc' is your
friend in leap.
