B Ir Ru Ru
Ru2IrB crystallizes in the monoclinic Cm space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 1-coordinate geometry to three equivalent Ru(2) and one B(1) atom. There is one shorter (1.72 Å) and two longer (2.24 Å) Ru(1)-Ru(2) bond lengths. The Ru(1)-B(1) bond length is 1.60 Å. In the second Ru site, Ru(2) is bonded in a 4-coordinate geometry to three equivalent Ru(1) and one Ir(1) atom. The Ru(2)-Ir(1) bond length is 2.30 Å. Ir(1) is bonded in a 1-coordinate geometry to one Ru(2) and one B(1) atom. The Ir(1)-B(1) bond length is 2.14 Å. B(1) is bonded in a 2-coordinate geometry to one Ru(1) and one Ir(1) atom.
