Crystal structure and Hirshfeld analysis of poly[bis-(<i>N</i>,<i>O</i>-di-methyl-hydroxyl-ammonium) [di-μ₂-iodido-di-iodido-plumbate(II)]].

ABSTRACT: The title compound, {(C₂H₈NO)₂[PbI₄]} _n , represents a layered organic-inorganic perovskite, crystallizing in space group C2/c. The asymmetric unit comprises one N,O-di-methyl-hydroxyl-ammonium cation, one Pb²⁺ cation located on a twofold rotation axis, and two iodide anions. The Pb²⁺ cation is coordinated by six iodido ligands, generating a slightly distorted octa-hedral {PbI₆} unit. The octa-hedra are connected by corner-sharing of equatorial I^- ligands to form polymeric inorganic sheets extending parallel to the ab plane. These sheets are separated by double layers of the organic cations, producing a typical di-periodic perovskite-type arrangement
