As you can clearly see in the high quality diagram above, I'm looking for a way to get the nitrogen and hydrogen bonded like that in chemfig.

You're looking for \chemabove{<atom>}{<above>}
:
\documentclass{article}
\usepackage{chemfig}
\begin{document}
\chemfig{R^1-[:30]\chemabove{N}{H}-[:-30]R^2}
\end{document}
Just for the record: there's also \chembelow{<atom>}{<below>}
. I've described them in a little more detail in my answer to “Changing space between atoms in Chemabove”
