【Abstract】 Solvothermal technique was used for the synthesis of (EnH 2) 2Ge 2S 6 and the crystal structure was determined by single crystal X-ray diffraction method. The compound comprises of isolated diborane-like Ge 2S 4- 6 formed by edge-sharing of two tetrahedral GeS 4. The atoms in Ge 2S 4- 6 are located in two orthogonal planes, two Ge atoms and bridging sulfur atoms are in one plane and terminal sulfurs and Ge in the other one. The compound belongs to the monoclinic system, space group P2(1)/n, with a=0.671 25(5) nm, b=1.122 90(4) nm, c=1.075 18(4) nm, β=92.288(2)°, Z=2; V=0.809 77 nm3. DSC-TG studies show that the compound is stable below 200 ℃.更多还原
