RuIrB crystallizes in the trigonal R3m space group. Ru(1) is bonded in a single-bond geometry to three equivalent Ir(1) and one B(1) atom. All Ru(1)-Ir(1) bond lengths are 2.17 Å. The Ru(1)-B(1) bond length is 0.18 Å. Ir(1) is bonded in a 7-coordinate geometry to three equivalent Ru(1) and four equivalent B(1) atoms. There are three shorter (2.17 Å) and one longer (3.00 Å) Ir(1)-B(1) bond length. B(1) is bonded in a single-bond geometry to one Ru(1) and four equivalent Ir(1) atoms.
