Abstract

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.
