Bis(ethylenediammonium) tetradecaborate

Abstract

The title compound, 2C2H10N22+·B14O20(OH)64−, consists of a centrosymmetric tetradecaborate anion and two ethylenediammonium cations. The anions are interconnected through strong O—H...O hydrogen bonds into a three-dimensional supramolecular network with channels along [100], [010], [001] and [111]. The diprotonated cations reside in the channels and interact with the inorganic framework by extensive N—H...O hydrogen bonds.
