Аннотация
Quaternary sulfide Ba2.77SnSb2.16S8 is prepared from stoichiometric mixtures of Ba, Sn, Sb, and S at 1223 K in an evacuated silica tube. Ba2.77SnSb2.16S8 crystallizes in the orthorhombic Pnma space group with a = 11.7125(18) Å, b = 4.3870(9) Å, c = 29.778(5) Å, V = 1530.1(5) Å3, Dcalc = 4.418 g/cm3 and Z = 4. This structure contains triple chains of distorted SbS5 square pyramids, which are interconnected via edge-sharing to form one-dimensional (1D) ribbons along the [010] direction. These ribbons are parallel to the chains of SnS4 tetrahedra separated by Ba2+ cations. The optical gap of 1.50 eV for Ba2.77SnSb2.16S8 is deduced from UV/Vis reflectance spectroscopy.
