Bis(pentane-1,5-diammonium) decaiodotriplumbate(II).

The title compound, [(NH(3)C(5)H(10)NH(3))(2)[Pb(3)I(10)]](n), crystallizes as an organic-inorganic hybrid. As such, the structure consists of extended chains of [Pb(3)I(10)](n)(4n-) ions extending along [111]. The asymmetric unit contains two independent Pb atoms: one is in a general position and the other is on an inversion centre. Each Pb atom is octahedrally coordinated by six iodide ions and exhibits both face- and edge-sharing with adjacent atoms in the inorganic chain. The organic counter-ion, viz. pentane-1,5-diammonium, lies in channels formed by the chains and interacts with these chains via N-H.I hydrogen bonding.
