Abstract

The crystal structures of three new hybrid organic-inorganic lead halide compounds [IqH]PbI₃, [4MiH]PbI₃, and [BzH]PbI₃ ([IqH⁺] = isoquinolinium, [4MiH⁺] = 4-methylimidazolium, [BzH⁺] = benzotriazolium) have been determined by single crystal x-ray diffraction. All three compounds have the same generic formula as perovskite, ABX₃, but adopt a rare non-perovskite structure built from one dimensional (1D) edge-sharing octahedral chains. The bandgap of each compound was investigated by solid UV–Vis spectra. In comparison with previously reported hybrid compounds containing the same type of octahedral chains, [C₁₀H₇CH₂NH₃]Pbl₃ and (C₇H₇N₂)PbI₃, all three new compounds have lower bandgaps (<2.4 ev), indicating that they may be promising for photovoltaic application.
