In2Bi crystallizes in the hexagonal P-6m2 space group. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted trigonal planar geometry to three equivalent Bi(1) atoms. In the second In site, In(2) is bonded in a 8-coordinate geometry to two equivalent In(2) and six equivalent Bi(1) atoms. Bi(1) is bonded in a distorted trigonal planar geometry to three equivalent In(1), six equivalent In(2), and two equivalent Bi(1) atoms.
In2Bi crystallizes in the hexagonal P-6m2 space group. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted trigonal planar geometry to three equivalent Bi(1) atoms. All In(1)-Bi(1) bond lengths are 3.17 Å. In the second In site, In(2) is bonded in a 8-coordinate geometry to two equivalent In(2) and six equivalent Bi(1) atoms. Both In(2)-In(2) bond lengths are 3.35 Å. All In(2)-Bi(1) bond lengths are 3.58 Å. Bi(1) is bonded in a distorted trigonal planar geometry to three equivalent In(1), six equivalent In(2), and two equivalent Bi(1) atoms.
