Abstract:
The title complex, (C(5)H(7)N(2))[PbI(3)], consists of a 1-amino-pyridinium cation, disordered about a mirror plane, and a [PbI(3)](-) anion. The Pb(2+) ion (site symmetry ) is surrounded by six I atoms in a slightly distorted octa-hedral coordination. The PbI(6) octa-hedra share faces, building up (∞) (1)[PbI(6/2)] chains running along [010]. The cations are situated between the chains. Coulombic attractions and van der Waals inter-actions between the inorganic and organic components are mainly responsible for the cohesion of the structure.
