Dy(IrB)2 crystallizes in the triclinic P1 space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 4-coordinate geometry to one Ir(1), one Ir(3), one Ir(4), one B(1), one B(3), and two equivalent B(4) atoms. The Dy(1)-Ir(1) bond length is 2.64 Å. The Dy(1)-Ir(3) bond length is 2.00 Å. The Dy(1)-Ir(4) bond length is 1.91 Å. The Dy(1)-B(1) bond length is 3.17 Å. The Dy(1)-B(3) bond length is 2.36 Å. There is one shorter (2.64 Å) and one longer (3.33 Å) Dy(1)-B(4) bond length. In the second Dy site, Dy(2) is bonded in a 2-coordinate geometry to one Ir(1), one Ir(4), one B(1), one B(2), one B(3), and two equivalent B(4) atoms. The Dy(2)-Ir(1) bond length is 2.54 Å. The Dy(2)-Ir(4) bond length is 2.64 Å. The Dy(2)-B(1) bond length is 2.69 Å. The Dy(2)-B(2) bond length is 2.36 Å. The Dy(2)-B(3) bond length is 1.99 Å. There is one shorter (3.17 Å) and one longer (3.20 Å) Dy(2)-B(4) bond length. There are four inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 4-coordinate geometry to one Dy(1), one Dy(2), one Ir(2), and one B(1) atom. The Ir(1)-Ir(2) bond length is 1.18 Å. The Ir(1)-B(1) bond length is 2.56 Å. In the second Ir site, Ir(2) is bonded in a 1-coordinate geometry to one Ir(1) atom. In the third Ir site, Ir(3) is bonded in a 2-coordinate geometry to one Dy(1), one Ir(4), and one B(1) atom. The Ir(3)-Ir(4) bond length is 1.18 Å. The Ir(3)-B(1) bond length is 2.81 Å. In the fourth Ir site, Ir(4) is bonded in a 4-coordinate geometry to one Dy(1), one Dy(2), one Ir(3), and one B(4) atom. The Ir(4)-B(4) bond length is 2.56 Å. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 5-coordinate geometry to one Dy(1), one Dy(2), one Ir(1), one Ir(3), and one B(3) atom. The B(1)-B(3) bond length is 2.20 Å. In the second B site, B(2) is bonded in a 1-coordinate geometry to one Dy(2) and one B(4) atom. The B(2)-B(4) bond length is 2.20 Å. In the third B site, B(3) is bonded in a 2-coordinate geometry to one Dy(1), one Dy(2), one B(1), and one B(4) atom. The B(3)-B(4) bond length is 1.97 Å. In the fourth B site, B(4) is bonded in a 7-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), one Ir(4), one B(2), and one B(3) atom.
