【Abstract】 An open-framework [Me4N]2HgGe4S10 (1) was solvothermally synthesized and characterized by single crystal diffraction, IR and DSC-TG techniques. Compound 1 was built up from supertetrahedra 4 Ge 4 S1 0- and HgS4, and has 1D channels with pore sizes of 0.94 nm×0.65 nm along direction a or b. TG-DSC results indicated that 1 has a good thermal stability in a nitrogen. Crystal data for 1: Mr=957.55, space group I-4, a=0.92687(8) nm, c=1.43739(12) nm, V=1.23484(18) nm3, Z=2, Mo Kα λ=0.071073 nm, R1=0.057, wR2=0.1374 for 906 reflections with I>2σ(I).更多还原
