Bis(propane-1,2-diammonium) hexaiodoplumbate(II) trihydrate

D. G. Billing and A. Lemmerer

Abstract: The title compound, [NH₃CH₂CH(NH₃)CH₃]₂[PbI₆]·3H₂O, crystallizes as an organic-inorganic hybrid, consisting of alternating inorganic and organic layers. The ionic layer consists of isolated [PbI₆]^4- octahedra. The hydrocarbon layer has one propane-1,2-diammonium cation in the asymmetric unit which links to the ionic layer via hydrogen bonding. Two solvent water molecules lie between the anions and cations. The Pb atom lies on a centre of inversion.
