Materials Data on InBiSe3 by Materials Project

InBiSe3 crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three InBiSe3 sheets oriented in the (0, 0, 1) direction. In3+ is bonded to six Se2- atoms to form InSe6 octahedra that share corners with three equivalent BiSe6 octahedra, edges with three equivalent BiSe6 octahedra, and edges with six equivalent InSe6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are three shorter (2.71 Å) and three longer (2.99 Å) In–Se bond lengths. Bi3+ is bonded to six Se2- atoms to form BiSe6 octahedra that share corners with three equivalent InSe6 octahedra, edges with three equivalent InSe6 octahedra, and edges with six equivalent BiSe6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are three shorter (2.86 Å) and three longer (3.11 Å) Bi–Se bond lengths. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent In3+ atoms. In the second Se2- site, Se2- is bonded in a 3-coordinate geometry to three equivalent Bi3+ atoms. In the third Se2- site, Se2- is bonded to three equivalent In3+ and three equivalent Bi3+ atoms to form edge-sharing SeIn3Bi3 octahedra.

Materials Data on In(BiSe2)3 by Materials Project

InBiSe3Bi2Se3 is MAX Phase-like structured and crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three Bi2Se3 sheets oriented in the (0, 0, 1) direction and three InBiSe3 sheets oriented in the (0, 0, 1) direction. In each Bi2Se3 sheet, there are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded to six Se2- atoms to form a mixture of edge and corner-sharing BiSe6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are three shorter (2.88 Å) and three longer (3.09 Å) Bi–Se bond lengths. In the second Bi3+ site, Bi3+ is bonded to six Se2- atoms to form a mixture of edge and corner-sharing BiSe6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are three shorter (2.88 Å) and three longer (3.11 Å) Bi–Se bond lengths. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 3-coordinate geometry to three equivalent Bi3+ atoms. In the second Se2- site, Se2- is bonded in a 3-coordinate geometry to three equivalent Bi3+ atoms. In the third Se2- site, Se2- is bonded to six Bi3+ atoms to form edge-sharing SeBi6 octahedra. In each InBiSe3 sheet, In3+ is bonded to six Se2- atoms to form InSe6 octahedra that share corners with three equivalent BiSe6 octahedra, edges with three equivalent BiSe6 octahedra, and edges with six equivalent InSe6 octahedra. The corner-sharing octahedral tilt angles are 2°. There are three shorter (2.73 Å) and three longer (3.01 Å) In–Se bond lengths. Bi3+ is bonded to six Se2- atoms to form BiSe6 octahedra that share corners with three equivalent InSe6 octahedra, edges with three equivalent InSe6 octahedra, and edges with six equivalent BiSe6 octahedra. The corner-sharing octahedral tilt angles are 2°. There are three shorter (2.88 Å) and three longer (3.12 Å) Bi–Se bond lengths. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 3-coordinate geometry to three equivalent Bi3+ atoms. In the second Se2- site, Se2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent In3+ atoms. In the third Se2- site, Se2- is bonded to three equivalent In3+ and three equivalent Bi3+ atoms to form edge-sharing SeIn3Bi3 octahedra.
