Hybrid Iodoplumbates with Metal Complexes: Syntheses, Crystal Structures, Band Gaps and Photoelectric Properties

Abstract

With the in situ-generated [Pb(MCP)4]2+ (HMCP+ = 1-methyl-4-(carboxyl)pyridinium) or [M(phen)3]2+ (M = Co, Fe and Ni; phen = 1,10-phenanthroline) complexes as structural directing agents and charge-balancing ions, we solvothermally synthesized and structurally characterized four new organic−inorganic hybrid iodoplumbates. Compound K2[Pb(MCP)4]Pb3I10 (1) represents the first K+ and [Pb(MCP)4]2+ co-templated hybrid haloplumbate, and exhibits a curve-like anionic layer of [Pb3I10]n4n−. Compounds [M(phen)3]Pb2I6•CH3CN (M = Co (2), Fe (3) and Ni (4)) are isostructural phases, and feature a one-dimensional (1D) [Pb2I6]n2n− anionic chain characteristic of pyramid-like [PbI5] units. The optical property studies show that compounds 1−4 possess semiconductor behaviors with the band gaps of 1.98−2.68 eV. In addition, the title compounds exhibited interesting photoelectrical responsive properties, with the photocurrent density in the order of 1 > 3 > 2 > 4. The thermal stabilities of the title compounds 1−4, as well as the theoretical band structure and density of states (DOS) of compounds 1 and 2 have also been studied.
