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 1 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···I and N‐H···Se H‐bonds, namely extended 3‐D network structure for 1 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.
