Bi B Ru Ru Ru Ru
Ru4BBi crystallizes in the trigonal R3m space group. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a 6-coordinate geometry to three equivalent Ru(1) and three equivalent Bi(1) atoms. All Ru(2)-Ru(1) bond lengths are 1.39 Å. All Ru(2)-Bi(1) bond lengths are 3.21 Å. In the second Ru site, Ru(1) is bonded in a 2-coordinate geometry to one Ru(2), two equivalent Ru(1), two equivalent B(1), and one Bi(1) atom. Both Ru(1)-Ru(1) bond lengths are 0.80 Å. Both Ru(1)-B(1) bond lengths are 2.81 Å. The Ru(1)-Bi(1) bond length is 1.84 Å. B(1) is bonded in a 6-coordinate geometry to six equivalent Ru(1) atoms. Bi(1) is bonded in a 6-coordinate geometry to three equivalent Ru(1) and three equivalent Ru(2) atoms.
