“…12) for both compounds. The unit cell volume V of Bi 2 Rh 3 Se 2 was 1144–1152 Å 3 for the case of β ∼ 90°; a = 11.414(10) Å, b = 8.3709(9) Å, c = 11.989(1) Å, and β = 89.153(3)° in ref , a = 11.416(1) Å, b = 8.365(1) Å, c = 11.982(2) Å, and β = 89.10(3)° in ref , and a = 11.4316(7) Å, b = 8.3872(4) Å, c = 12.0157(3) Å, and β = 89.225(4)° in ref , while the value of V for Bi 2 Pd 3 Se 2 determined in this study was 612.30(2) Å 3 for the case of β ∼ 133° ( a = 11.8156(5) Å, b = 8.4889(3) Å, c = 8.4686(3) Å, and β = 133.88(1)°). In addition, a study indicated that β ∼ 134° was also an optimal lattice choice even for the crystal lattice of Bi 2 Rh 3 Se 2 where a = 11.413(1) Å, b = 8.368(2) Å, c = 8.336(1) Å, and β = 134.05(4)° .…”
