Abstract

The title compound, (C12H16N2)2[PbBr6], is an organic–inorganic salt, with two doubly protonated N-(1-naphthyl)ethylenediammonium cations and one octahedral hexabromidoplumbate(II) anion. The PbII atom is located on a centre of inversion. The crystal structure consists of alternating inorganic and organic layers parallel to the bc plane. Face-to-face aromatic stacking interactions [centroid–centroid distance = 3.505 (5) Å] occur between parallel naphthalene systems in the organic layers, and N—H⋯Br hydrogen bonds between the cations and anions stabilize the crystal structure.
