Structural diversity in substituted-pyridinium iodo- and bromoplumbates: a matter of halide and temperature

Author affiliations

Abstract

Nine different monosubstituted pyridinium cations have been used for the synthesis of 22 new hybrid iodo- and bromoplumbates. Different frameworks can be obtained depending not only on the position (ortho-, meta- or para-), or nature (Br, Cl or Me) of the substituent but also on the temperature of the reaction. Out of the 22 new compounds synthesized, 16 are 1D systems with formula APbX3 (A = monosubstituted pyridinium cation, X = iodide or bromide), three are 2D systems type A2PbX4 and three are 2D systems type A4Pb3I10. 15 of these compounds have been characterized by single crystal X-ray diffraction. The thermal stability as well as the optical properties of all compounds have been studied.
