Abstract: Solvothermal technique was used for the synthesis of (EnH2)2Ge2S6 and the crystal structure was determined by single crystal X-ray diffraction method. The compound comprises of isolated diborane-like Ge2S64- formed by edge-sharing of two tetrahedral GeS4. The atoms in Ge2S64- 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 ℃.
