| Abstract: | A new selenidostannate Cd(tren)SnSe3(tren=tris(2-aminoethyl) amine) was synthesized by solvothermal method .The single crystal X-ray diffraction analysis show that the compound crystallizes in the triclinic, space group P-1, with a=0.7752(3) nm, b=0.8128(2) nm, c=1.2467(4) nm,α=97.299(19)°,β=103.639(18)°,γ=107.325(17)°, V=0.7121(4) nm3, Z=2, Dc =2.865 Mg· m-3 , Mr =614.21, F(000)=564.The compound is a zero-dimensional cluster structure and is formed by connecting two Cd(tren)]2 +units from the trans-terminal Se atoms of the Sn2Se6] unit.The results of UV-Vis diffuse reflectance spectra show that the band gap of the compound is 1.80 eV. |
