Three one-dimensional (1-D) structure quaternary selenidoarsenates containing mercury [TM(en)3][HgAs2Se4] (TMMn, Ni, Zn) (en = ethylenediamine) were synthesized by solvothermal method. Compounds 1–3 are isostructural and single crystal X-ray diffraction results show that 1–3 belong to the Monoclinic crystal system, P21/c space group. 1–3 consists of a 1-D [HgAs2Se4]2− anionic chain and the complex cation
通过溶剂热法合成了三种一维 (1- D ) 结构的含汞 [TM(en) 3 ][HgAs 2 Se 4 ] (TM Mn, Ni, Zn) (en = 乙二胺) 的季硒代砷酸盐。化合物1 - 3是同构和单晶X射线衍射结果表明,1 - 3属于单斜晶系,P 2 1 / ç空间群。1 – 3由 1- D [HgAs 2 Se 4 ] 2-阴离子链和复合阳离子 [TM(en) 3 ] 2+,其中 [HgAs 2 Se 4 ] 2-链由四面体 [HgSe 4 ]通过 As-Se 键连接到二聚体 As 2 4+形成。它们的吸收边分别为2.07 eV( 1 )、2.15 eV( 2 )和2.03 eV( 3 ),表明这三种化合物都可以作为半导体材料。此外,还研究了它们的热稳定性、光催化、光电流响应。
