Diisopropylammonium hydrogen difluoride.
By the reaction of diisopropylamine with concentrated hydrofluoric acid, the title compound, C(6)H(16)N(+).HF(2)(-), was synthesized. The cations and anions are connected via hydrogen bonds to form chains along [100]. The interlocked polymeric zigzag chains are hexagonally surrounded by six neighbouring chains. The F(-) anion is strongly hydrogen bonded to HF [F-H 0.98 (4), H...F 1.34 (4), F...F 2.3125 (16) A and F-H...F 174 (3) degrees]; a better description is that of a non-centred hydrogen difluoride anion.
