Symmetric bisimidazolium picrates were synthesized by the quaternization of bisimidazolylmethylene and a metathesis reaction with silver picrate. The symmetric structures of the new picrate salts were confirmed by 1H and 13C NMR spectral analysis and ESI‐MS. The structures of compounds 3a and 4a were also confirmed by X‐ray single crystal diffusion. The thermal properties of the compounds were determined...
