Abstract
A new organic-inorganic hybrid, [Pb(2)I(4)(C(4)H(13)N(3))](n), was obtained by the reaction of C(4)N(3)H(10) and PbI(2) at room temperature. The structure is a three-dimensional polymer resulting from the association of PbI(6) octa-hedra and a mixed lead organic-inorganic PbI(4)(C(4)N(3)H(13)) coordination polyhedron. Both Pb atoms, two I atoms and one N atom lie on a mirror plane. N-H⋯I hydrogen bonds further connect the organic unit and some I atoms.Entities:

| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
