摘要：

Novel organic-inorganic hybrid compounds, C10H10N2PbBr4 and C10H22N2PbBr4 were prepared and characterized by X-ray and optical measurements. The result of single crystal X-ray analysis showed that the inorganic region of C10H10N2PbBr4 consisted of one-dimensional chains of line-sharing PbBr6 octahedra, whereas that of C10H22N2PbBr4 consisted of two-dimensional sheets of corner-sharing PbBr6 octahedra. Each crystal exhibited an excitonic band at 307 nm for C10H10N2PbBr4 and 383 nm for C10H22N2PbBr4, which is attributed to the excitonic states of low-dimensional inorganic structures. These results indicate that the dimensional structure of these compounds can be systematically controlled by changing the chemical structure of organic ligands.
