Abstract
Rb2Bi8Se13 (I), Cs2Bi8Se13 (II), CsBi3.67Se6 (III), and BaBi2Se4 (IV) were synthesized by direct combination reactions of the A/Se (A = Rb, Cs, Ba) and Bi2Se3 at ≥650 °C. Their structures were determined by single-crystal X-ray diffraction. Rb2Bi8Se13 and Cs2Bi8Se13 are isostructural and crystallize in the monoclinic space group P21/m (No. 11) with a = 13.4931(4) A, b = 4.1558(3) A, c = 24.876(2) A, β = 96.571(4)°, R1 = 0.0577, and wR2 = 0.1159 [I > 2σ(I)] for I and a = 13.704(1) A, b = 4.1532(4) A, c = 25.008(2) A, β = 96.848(2)°, R1 = 0.0497, and wR2 = 0.1123 [I > 2σ(I)] for II. CsBi3.67Se6 crystallizes in the orthorhombic space group Pnma (No. 62) with a = 23.421(4) A, b = 4.1877(8) A, c = 13.710(3) A, R1 = 0.0611, and wR2 = 0.1384 [I > 2σ(I)]. BaBi2Se4 crystallizes in the hexagonal space group P63/m (No. 176) with a = 26.157(1) A, c = 4.3245(3) A, R1 = 0.0371, and wR2 = 0.0817 [I > 2σ(I)]. The structure of A2Bi8Se13 features a three-dimensional framework consisting of wide rectangular NaCl-type infini...
