In4PbBi3 crystallizes in the tetragonal I4/mcm space group. In(1) is bonded in a 8-coordinate geometry to three equivalent In(1), two equivalent Bi(1), and three equivalent Bi(2) atoms. Pb(1) is bonded to two equivalent Bi(1) and four equivalent Bi(2) atoms to form corner-sharing PbBi6 octahedra. The corner-sharing octahedral tilt angles range from 0-48°. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 10-coordinate geometry to eight equivalent In(1) and two equivalent Pb(1) atoms. In the second Bi site, Bi(2) is bonded in a 9-coordinate geometry to six equivalent In(1), two equivalent Pb(1), and one Bi(2) atom.
In4PbBi3 crystallizes in the tetragonal I4/mcm space group. In(1) is bonded in a 8-coordinate geometry to three equivalent In(1), two equivalent Bi(1), and three equivalent Bi(2) atoms. There is one shorter (3.32 Å) and two longer (3.45 Å) In(1)-In(1) bond lengths. Both In(1)-Bi(1) bond lengths are 3.42 Å. There are two shorter (3.34 Å) and one longer (3.40 Å) In(1)-Bi(2) bond length. Pb(1) is bonded to two equivalent Bi(1) and four equivalent Bi(2) atoms to form corner-sharing PbBi6 octahedra.
