Hydrogen-bonded cubanes and ladder fragments by analogy with the inorganic solid state.
By application of an analogy with the structures of alkali-metal phosphinimides, two hydrogen-bonded cubanes, [Ph(3)CNH(3)(+)X(-)](4) (X = Cl, Br), and one unprecedented four-rung ladder fragment, [Ph(3)CNH(3)(+)I(-)](4), have been prepared in the organic solid state.
