InSnBr3 crystallizes in the trigonal R3c space group. In(1) is bonded in a 3-coordinate geometry to three equivalent Br(1) atoms. Sn(1) is bonded to six equivalent Br(1) atoms to form corner-sharing SnBr6 octahedra. The corner-sharing octahedral tilt angles are 31°. Br(1) is bonded in a 2-coordinate geometry to one In(1) and two equivalent Sn(1) atoms.
InSnBr3 crystallizes in the trigonal R3c space group. In(1) is bonded in a 3-coordinate geometry to three equivalent Br(1) atoms. All In(1)-Br(1) bond lengths are 3.32 Å. Sn(1) is bonded to six equivalent Br(1) atoms to form corner-sharing SnBr6 octahedra. The corner-sharing octahedral tilt angles are 31°. There are three shorter (2.87 Å) and three longer (3.16 Å) Sn(1)-Br(1) bond lengths. Br(1) is bonded in a 2-coordinate geometry to one In(1) and two equivalent Sn(1) atoms.
