 Title    Preparation and Characterization of [C6H5CH2 NH3]2PbI4, [C6H5CH2 CH2 SC(NH2 )2]3PbI5 and [C10H7CH2NH3]PbI3 Organic-Inorganic Hybrid Compounds  
 Abstract    The preparation, crystal structures, optical absorption spectra, and photoluminescence spectra of the title compounds are reported. The compounds were prepared in single crystal form. [CftHsCHiNH.^PbL consists of anionic perovskite sheets of corner-sharing Pbl6 octahedra, which alternate with the C ö H s C ^ N H ^ sheets. [ C ftH s C ^ C ^ S Q N H i^ b P b ls consists of zig-zag chains of anionic corner sharing Pbl6 octahedra separated by C6H5CH 2CH 2SC(NH2)2 cations. [CioH7CH 2N H 3]Pbl3 consists of twin chains of edge-sharing P b^ octahedra separated by C 10H7CH2NH3 cations. The compounds are thus low-dimensional systems. The excitonic spectra were observed in all cases, even at room temperature, and the possibility of organic-inorganic excitonic interactions is discussed.
