Abstract

Two new cobalt phosphite-oxalates, formulated as Co₂(H₂PO₃)₂(C₂O₄)₃(C₆N₂H₁₆)₂ (1) and Co₂(H₂PO₃)₂(C₂O₄)₂(C₆N₂H₁₆) (2), have been synthesized under solvent-free conditions. Single-crystal X-ray diffraction analysis reveals that compound 1 has a 1D chain-like structure decorated with phosphite groups. It is noted that there are two coordination modes of oxalate ligands in the structure. Compound 2 is a 2D distorted honeycomb-like layered open-framework structure with 12-membered ring windows. Notably, compound 2 possesses room temperature proton conductivity. Extensive hydrogen bonds existing between the host framework and guest part play an important role as proton-conducting pathways.
