The material structure described by Tb6IrBr10 crystallizes in the triclinic P-1 space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to one Ir(1), one Br(1), one Br(4), one Br(5), and two equivalent Br(3) atoms to form a mixture of edge and corner-sharing TbIrBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. In the second Tb site, Tb(2) is bonded to one Ir(1), one Br(2), one Br(4), one Br(5), and two equivalent Br(1) atoms to form a mixture of edge and corner-sharing TbIrBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. In the third Tb site, Tb(3) is bonded to one Ir(1), one Br(1), one Br(3), one Br(4), and two equivalent Br(2) atoms to form a mixture of edge and corner-sharing TbIrBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. Ir(1) is bonded in an octahedral geometry to two equivalent Tb(1), two equivalent Tb(2), and two equivalent Tb(3) atoms. There are five inequivalent Br sites. In the first Br site, Br(1) is bonded in a see-saw-like geometry to one Tb(1), one Tb(3), and two equivalent Tb(2) atoms. In the second Br site, Br(2) is bonded in a T-shaped geometry to one Tb(2) and two equivalent Tb(3) atoms. In the third Br site, Br(3) is bonded in a T-shaped geometry to one Tb(3) and two equivalent Tb(1) atoms. In the fourth Br site, Br(4) is bonded in a 3-coordinate geometry to one Tb(1), one Tb(2), and one Tb(3) atom. In the fifth Br site, Br(5) is bonded in an L-shaped geometry to one Tb(1) and one Tb(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
