Abstract

One quaternary selenidoantimonate of [Mn(en)₃]CdSb₂Se₅ (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 C2/c. Its structure consists of infinite 1D [CdSb₂Se₅]_n²ⁿ⁻ anionic chains and [Mn(en)₃]²⁺ cations. Meanwhile, “Z” shaped eight-membered [Cd₂Sb₂Se₄] and six-membered [CdSb₂Se₃] 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]CdSb₂Se₅. 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.

一维[Mn(en)3]CdSb2Se5的溶剂热合成及表征

在1,2-丙二胺条件下，采用温和溶剂热法制备了[Mn(en)3]CdSb2Se5(1)季硒锑酸盐(en =乙二胺)。单晶x射线衍射分析表明，化合物1在单斜空间群C2/c中结晶。其结构由无限的一维[CdSb2Se5]n2n−阴离子链和[Mn(en)3]2+阳离子组成。同时，“Z”型八元[Cd2Sb2Se4]环和六元[CdSb2Se3]环交替存在。根据紫外-可见吸收光谱估计，1的带隙为2.58 eV。通过光电测试，化合物1也表现出快速的响应和良好的重现性。此外，还研究了1的磁性和其他性能。摘要本文描述了[Mn(en)3]CdSb2Se5的合成、晶体结构、单晶x射线衍射、元素分析、光电响应、热重分析、磁性能、红外光谱和紫外-可见漫反射光谱。对化合物1的光电响应进行了探索，发现了一条高度重复且稳定的光电流曲线，表明1是典型的p型半导体。此外，还对化合物1的磁性进行了研究，结果表明化合物1具有反铁磁性。
