Sc2TiIr5B2 crystallizes in the tetragonal P4/mbm space group. Sc(1) is bonded in a 13-coordinate geometry to two equivalent Ir(2), eight equivalent Ir(1), and three equivalent B(1) atoms. Ti(1) is bonded in a body-centered cubic geometry to eight equivalent Ir(1) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to four equivalent Sc(1), two equivalent Ti(1), and two equivalent B(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to four equivalent Sc(1) and four equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1), two equivalent Ir(2), and four equivalent Ir(1) atoms.
Sc2TiIr5B2 crystallizes in the tetragonal P4/mbm space group. Sc(1) is bonded in a 13-coordinate geometry to two equivalent Ir(2), eight equivalent Ir(1), and three equivalent B(1) atoms. Both Sc(1)-Ir(2) bond lengths are 2.81 Å. There are four shorter (2.88 Å) and four longer (2.98 Å) Sc(1)-Ir(1) bond lengths. There is one shorter (2.69 Å) and two longer (2.83 Å) Sc(1)-B(1) bond lengths. Ti(1) is bonded in a body-centered cubic geometry to eight equivalent Ir(1) atoms.
