A molecular salt with a bulky cation and anion, (H2bipip)-(H)2[Fe(CN)6] (1) (H2bipip2+: 4,4¤-bipiperidine-1,1¤-diium), has been prepared. The salt comprises protons (H+) as counter cations. Single-crystal X-ray structure analysis revealed that the proton is trapped between two cyanido ligands of [Fe(CN)6]41 anions, forming a very short N£H+£N hydrogen bond.
