A series
of open-framework metal oxalates (metal = Zn, Co, Mn, Bi, In) were
prepared under solvent-free conditions by a supramolecular templating
approach. These compounds have cationic, anionic, and neutral frameworks
with pore apertures ranging from small 8-membered rings (8 MRs) to
extra-large 16 and 20 MRs. The zinc oxalate exhibits a proton conductivity
of 2.6 × 10–3 S cm–1 at 60
°C under 98% relative humidity.
