Solvo-thermal reaction Semiconductor Metal chalcogenide Crystal structure

摘要

Abstract

The solvo-thermal technique is used for the synthesis of [Mn(en)3]Te4(I).The crystal structure has been determined by single crystal X-ray diffraction techniques.The crystal belongs to the monoclinic, space groupp21/cwith unit cell:a=0.846 1(1),b=1.565 3(2),c =1.426 9(2) nm,α=90°,β=91.37(1) (3)°,γ=90°,V=1.889 3(4) nm3,andZ=4.The results show that the structure contains a linear chain Zintl anion,[Te4]2-and a complex cation, [Mn(en)3]2+. Optical studies have been performed on the powder sample of I, suggesting that the compound is a semiconductor with a band gap of 0.73 eV. The semiconductor properties for MnQ2(Q=S,Se,Te) and [Mn(en)3]Te4have been discussed by molecular orbital theory.
