Abstract Reactions of R, R-, cis- and trans-1,2-cyclohexanediamine with lead(II) iodide in concentrated HI aqueous solution afforded three organic–inorganic hybrid compounds, [(R, R-1,2-C6H16N2)PbI4] (1), [(cis-1,2-C6H16N2)2Pb2I8]·2H2O (2) and [(trans-1,2-C6H16N2)2PbI6]·2H2O (3), respectively. Single-crystal X-ray diffraction revealed that the inorganic components in 1–3 are constructed with a 2-D monolayer perovskite sheet, a 1-D zigzag chain and only a concrete [PbI6] octahedron which were caused by the different configurations of 1,2-cyclohexanediamine. In addition, 1–3 have been investigated by UV–vis, TG analysis and fluorescence spectra. Graphical Abstract
