The crystal structure consists of tetrahedral [ SbS4 ]^3- anion, octahedral [ Fe （en）3 ]^2＋ complex cation and protonated [ Hen]^＋ cation. A three -dimensional supramolecular network is formed by the intermolecular N -H…Se and N -H…N hydrogen bonds between anions and cations. The crystal band gap is at 2. 52 eV. On heating, the compound losses organic components in two steps under N2 atmospere.
