Abstract: | BaB2S4: The first non‐oxidic Chalcogenoborate with Boron in a trigonal‐planar and tetrahedral Coordination Hitherto we know boron in a trigonal‐planar and a tetrahedral coordination within one crystal structure from boron oxides in various compounds. With the novel bariummetathioborate BaB2S4 we now report a crystal structure containing BS3 and BS4 units in the ratio 1 : 1 forming infinite chains along [001]. BaB2S4 was synthesized in a solid state reaction at a temperature of 800 °C from barium sulfide, amorphous boron and sulfur and crystallizes in the monoclinic space group Cc (no. 9) with the following lattice parameters: a = 6.6465(5) Å, b = 15.699(1) Å, c = 6.0306(5) Å, β = 110.96(1)°, Z = 4. |
