Sn5(Ir3B)2 crystallizes in the hexagonal P-62m space group. Ir(1) is bonded in a 7-coordinate geometry to one B(1), one B(2), two equivalent Sn(1), and three equivalent Sn(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted pentagonal pyramidal geometry to six equivalent Ir(1) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to six equivalent Ir(1) and three equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to six equivalent Ir(1) atoms. In the second Sn site, Sn(2) is bonded in a 7-coordinate geometry to six equivalent Ir(1) and one B(2) atom.
