16. Compound1was synthesized using three different methods: method (a) K2CO3(0.03 mol, 4.146 g), Sn (0.03 mol, 3.561 g), Sb (0.06 mol, 7.306 g), and S (0.19 mol, 6.092 g) were combined and loaded in a 50 mL grinding jar under nitrogen atmosphere in a glovebox. The mixture was ball-milled at 100 rpm for 1 min and at 250 rpm for 30 minutes. 3 g of the ball-milled mixture was placed in a 13 mm outer diameter (OD) carbon coated fused-silica tube under N2atmosphere. A rubber balloon was attached at the end of the reaction tube in order to accommodate the created pressure of the CO2evolution. The mixture was heated gradually to 200 °C where it was kept for 5 h before being successfully brought to 800 °C. It was kept at 800 °C for 8 h. A red glassy ingot was obtained by cooling at a rate of 40 °C/h to room temperature; method.
17. bA mixture of K2S (4 mmol, 0.4410 g), S (8 mmol, 0.2565 g), Sn (4 mmol, 0.4570 g), and Sb2S3(4 mmol, 1.3588 g) was sealed under vacuum (10–4Torr) in a 13 mm (OD) carbon coated fused-silica tube and heated (80 °C/h) to 800 °C. It was kept there for 24 h, followed by cooling to room temperature at 40 °C/h; method.
18. cCompound1was also synthesized by combining in a nitrogen-filled glovebox K2S (2 mmol, 0.2205 g), S (10 mmol, 0.3206 g), Sn (2 mmol, 0.2347 g), and Sb (4 mmol, 0.4870 g) with the same type of silica reaction vessel flame-sealed under vacuum, and same temperature profile as method b. The empirical formula for the products obtained from three methods was K2SnSb2S6based on EDS analyses. The product is a red ingot.
19. ausing Cs2S (1 mmol, 0.2205 g), S (5 mmol, 0.1620 g), Sn (1 mmol, 0.1187 g), and Sb (2 mmol, 0.2435 g) in accordance to the conditions and heating profile for the synthesis compound1; method.
20. bCs2CO3(0.03 mol, 9.775 g), Sn (0.03 mol, 3.561 g), Sb (0.06 mol, 7.306 g), and S (0.19 mol, 6.092 g) were combined and loaded in a 50 mL grinding jar under nitrogen atmosphere in a glove box. The mixture was ball-milled at 100 rpm for 1 min and at 250 rpm for 30 minutes. 3 g of the ball-milled mixture was placed in a 13 mm (OD) carbon coated fused-silica tube under N2atmosphere. A secured balloon was attached at the end of the reaction tube in order to absorb the created pressure of the CO2evolution. The mixture was heated gradually to 200 °C where it was kept for 5 h before being raised to 800 °C and kept for 8 h. An orange glassy ingot was obtained by cooling at a rate of 80 °C/h to room temperature. For the synthesis of compound3, a mixture of K2Se (2 mmol, 0.3143 g), Se (10 mmol, 0.7896 g), Sn (2 mmol, 0.2347 g), and Sb (4 mmol, 0.4870 g) was sealed under vacuum (10–4Torr) in a 13 mm (OD) carbon coated fused-silica tube and heated (80 °C/h) to 800 °C for 24 h, followed by cooling to room temperature at 40 °C/h. The product is a dark red-black ingot.
