Shape shifting : A novel pillared, solid organic–inorganic phase is prepared by stepwise double topotactic exchange of γ‐zirconium phosphate with pentaethylenglycol‐derived diphosphonic acid and hypophosphite. The interlayer distance of the title material sharply increases when treated with methylamine. This enormous sensitivity of microcrystalline porosity towards intercalation of small molecules has no precedent.
