Crystal structures and photocatalytic properties of two novel iodoplumbate hybrids templated by multivalent organic cations

Abstract

Two novel complexes based on multivalent organic cations and PbI₂, {(tbp)₂[Pb₃I₁₂]}_n (1) (tbp = 1,3,5-tri(N-pyridinium methyl)benzene tribromide) and {(tbpm)[Pb₃I₉]·H₂O}_n (2) (tbpm = 1,3,5-tri(4-methylpyridiniummethyl) benzene tribromide), have been synthesized and characterized by X-ray diffractometry. Compound 1 has a trinuclear structure and compound 2 presents a new 1D iodoplumbate. Photochemical studies reveal the good photocatalytic performances of the two iodoplumbate hybrids. Furthermore, the side chain's effect on the fabrication of the iodoplumbate and the photocatalytic performances was also investigated.
