| 英文摘要 | Four new chalcohalides, namely naba2sns4cl, kba2sns4cl, kba2sns4br, and csba2sns4cl, have been synthesized by the conventional high temperature solid-state reactions. they crystallize in three different space groups: space group i4/mcm for naba2sns4cl and kba2sns4cl, pnma for kba2sns4br, and p2(1)/c for csba2sns4cl. in all four compounds, the x- halide anions are only connected to six alkali metal or ba cations, and the sn atoms are only tetrahedrally enjoined to four s atoms. however, the m-x-ba pseudo layers and the sns4 tetrahedra are arranged in different ways in the three structural types, which demonstrates the interesting effect of ionic radii on the crystal structures. uv-vis-nir spectroscopy measurements indicate that naba2sns4cl, kba2sns4cl, kba2sns4br, and csba2sns4cl have band gaps of 2.28, 2.30, 1.95, and 2.06 ev, respectively.
