초록

The tetrahedral arrangement of hydrogen bonding donor and acceptor groups is used to rationalise the design of a diamondoid network; however, a single proton transfer renders the four sites inequivalent, and results in two polymorphs of the title molecular salt utilizing similar intermolecular synthons.
