Bis[N-(1-naphthyl)ethylenediammonium] hexaiodoplumbate(II)

Y.-Y. Zheng, G. Wu, H.-Z. Chen and M. Wang

Abstract: The title compound, (C₁₂H₁₆N₂)₂[PbI₆], is an organic-inorganic salt, with two doubly protonated N-(1-naphthyl)ethylenediamine groups as the cations and one octahedral hexaiodoplumbate(II) as the anion. The stucture consists of alternating inorganic and organic layers parallel to the bc plane. Simple face-to-face aromatic stacking interactions occur between parallel naphthalene systems in the organic layers, and N-HI hydrogen bonds between the ethylenediammonium groups and PbI₆^4- octahedra stabilize the structure. The slightly distorted PbI₆ octahedra are isolated from each other, with the Pb atom located on a centre of inversion.
