摘要

Two new indium selenides [In(en)(2)Se](2)-2I (1) and [In(teta)Se](2)-2I (2) (en = ethylenediamine, teta = triethylenetetramine) were obtained under mild solvothermal conditions and structurally characterized. Compounds I and 2 consist of unusual organic hybrid indium selenide cations and I- anions. These ions are assembled to two different supramolecular structures by N-H center dot center dot center dot I and N-H center dot center dot center dot Se H-bonds, namely extended 3-D network structure for I and extended sheet structure for 2. The optical band gaps of 2.92 eV for 1 and 3.15 eV for 2 were derived from optical absorption spectra. The thermal stability of 1 and 2 was investigated by thermogravimetric measurements.
