A solid-liquid method was used to synthesize bulk BaC6 graphite intercalation compound, allowing for crystal structure determination. The study found that BaC6 crystallizes in the hexagonal P6(3)/mmc space group based on X-ray diffraction data.
A solid-liquid method is used to synthesize the first stage bulk BaC6 graphite intercalation compound (GIC). This way of synthesis allows the preparation of bulk and massive samples useful for crystal structure determination. Through a eutectic medium LiCl-KCl, and by submerging a graphite platelet in barium-molten solution at 450 degrees C for several days, the bulk BaC6 compound is obtained and X-ray diffraction investigations allowed a complete structural study. The collected data certify that BaC6 crystallizes in the hexagonal P6(3)/mmc space group with the following parameters a = b = 430.6 pm and c = 1058.2 pm. (C) 2021 Elsevier Ltd. All rights reserved.
