The title complex, (C5H7N2)[PbI3], consists of a 1-aminopyridinium cation, disordered about a mirror plane, and a [PbI3]− anion. The Pb2+ ion (site symmetry overline{1}) is surrounded by six I atoms in a slightly distorted octahedral coordination. The PbI6 octahedra share faces, building up ∞1[PbI6/2] chains running along [010]. The cations are situated between the chains. Coulombic attractions and van der Waals interactions between the inorganic and organic components are mainly responsible for the cohesion of the structure.
