W2Ir3B5 crystallizes in the orthorhombic Imm2 space group. W(1) is bonded in a 6-coordinate geometry to three equivalent B(1) and three equivalent B(2) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted L-shaped geometry to two equivalent B(3) atoms. In the second Ir site, Ir(2) is bonded in a 4-coordinate geometry to one B(1), one B(2), and two equivalent B(3) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded in a 7-coordinate geometry to three equivalent W(1), one Ir(2), and three equivalent B(2) atoms. In the second B site, B(2) is bonded in a 7-coordinate geometry to three equivalent W(1), one Ir(2), and three equivalent B(1) atoms. In the third B site, B(3) is bonded in a 6-coordinate geometry to two equivalent Ir(1) and four equivalent Ir(2) atoms.
W2Ir3B5 crystallizes in the orthorhombic Imm2 space group. W(1) is bonded in a 6-coordinate geometry to three equivalent B(1) and three equivalent B(2) atoms.
