The one-dimensional organic–inorganic hybrid: catena-polybis­1-(3-ammonio­prop­yl)-1H-imidazolium iodidoplumbate(II)-tri-μ-iodido-plumbate(II)-tri-μ-iodido-iodidoplumbate(II)-di-μ-iodido

摘要

The organic–inorganic hybrid, {(C6H13N3)2[Pb3I10]}n, was obtained by the reaction of 1-(3-ammonio­prop­yl)imidazolium triiodide and PbI2 at room temperature. The structure contains one-dimensional {[Pb3I10]⁴⁻}n polymeric anions spreading parallel to [001], resulting from face–face–edge association of PbI6 distorted octa­hedra. One of the Pb^II cations is imposed at an inversion centre, whereas the second occupies a general position. N—H⋯I hydrogen bonds connect the organic cations and inorganic anions.
