An open-framework iron phosphate with large voids, exhibiting spin-crossover

Abstract

A novel iron phosphate, [(C₄N₃H₁₆)(C₄N₃H₁₅)]⁵⁺-[Fe₅F₄(H₂PO₄)(HPO₄)₃(PO₄)₃]^5–·H₂O, consisting of a Fe–O/F–Fe network crosslinked by PO₄ groups is shown to possess unusually large elliptical voids of 24 T atoms (T = Fe, P) and to exhibit a gradual low- to high-spin transformation.
