InBi3 crystallizes in the orthorhombic C222 space group. In(1) is bonded in a 6-coordinate geometry to two equivalent In(1) and four equivalent Bi(2) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to two equivalent Bi(1) and four equivalent Bi(2) atoms to form distorted corner-sharing BiBi6 pentagonal pyramids. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to two equivalent In(1), two equivalent Bi(1), and two equivalent Bi(2) atoms.
