High-pressure observation of elusive iodoplumbic acid in different hydronium-hydrate solid forms
Abstract
High-pressure and high-temperature isochoric crystallization combined with single-crystal X-ray diffraction revealed the proposed, but previously never demonstrated, hydronium acid hydrates of [PbI3]–, the closest forms of the elusive iodoplumbic acid. Depending on the pressure range, the reaction of PbI2 and aqueous concentrated hydriodic acid under isochoric conditions in a diamond anvil cell held between 0.11 and 1.20 GPa produces two hydrated acids with compositions [H3O][PbI3] · nH2O (n = 3, 4). Comprised of polymeric one-dimensional double-chain PbI3– anions, analogous to those seen in archetypal lead-halide perovskites RbPbI3, CsPbI3, these hydrates offer the first observation of the elusive iodoplumbic acid progenitor of hybrid lead perovskites. We also reveal the ‘hidden’ polymorph of lead(II) iodide, adopting a three-dimensional Pb-I bonded network, contrasting with the prototypic ambient-pressure layered PbI2 structure.
