One quaternary selenidoantimonate of [Mn(en) 3 ]CdSb 2 Se 5 ( 1 ) (en = ethylenediamine) was prepared under 1,2-propanediamine condition by mild solvothermal method. Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in the monoclinic space group C 2/c. Its structure consists of infinite 1D [CdSb 2 Se 5 ] n 2n− anionic chains and [Mn(en) 3 ] 2+ cations. Meanwhile, “Z” shaped eight-membered [Cd 2 Sb 2 Se 4 ] and six-membered [CdSb 2 Se 3 ] rings are alternately found. As estimated from UV–Vis absorption spectrum, the band gap of 1 is 2.58 eV. Compound 1 also showed rapid response and excellent reproducibility based on photoelectric test. In addition, the magnetic and other properties of 1 were studied. Graphical Abstract The manuscript describes the synthesis, crystal structure, single-crystal X-ray diffraction, elemental analysis, photoelectric response, thermogravimetric analysis, magnetic properties, infrared spectroscopy and UV-Vis diffuse reflectance spectroscopy of [Mn(en) 3 ]CdSb 2 Se 5 . The photoelectric response of compound 1 was explored, and a highly repetitive and stable photocurrent curve was found, indicating that 1 is a typical p-type semiconductor. In addition, the magnetism of compound 1 was also studied, which showed that 1 had antiferromagnetic behavior.
