Hydrogen-bonded cubanes and ladder fragments by analogy with the inorganic solid state
Abstract
By application of an analogy with the structures of alkali-metal phosphinimides, two hydrogen-bonded cubanes, [Ph3CNH3+X−]4 (X = Cl, Br), and one unprecedented four-rung ladder fragment, [Ph3CNH3+I−]4, have been prepared in the organic solid state.
