Bi Bi Ru Rh
RuRhBi2 crystallizes in the trigonal R3m space group. Ru(1) is bonded in a 1-coordinate geometry to four equivalent Rh(1), three equivalent Bi(2), and four equivalent Bi(1) atoms. There is one shorter (2.33 Å) and three longer (3.28 Å) Ru(1)-Rh(1) bond lengths. All Ru(1)-Bi(2) bond lengths are 3.22 Å. There are three shorter (2.93 Å) and one longer (3.22 Å) Ru(1)-Bi(1) bond length. Rh(1) is bonded in a 11-coordinate geometry to four equivalent Ru(1), three equivalent Bi(1), and four equivalent Bi(2) atoms. All Rh(1)-Bi(1) bond lengths are 3.22 Å. There are three shorter (2.93 Å) and one longer (3.22 Å) Rh(1)-Bi(2) bond length. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 11-coordinate geometry to four equivalent Ru(1), three equivalent Rh(1), and four equivalent Bi(2) atoms. There are three shorter (2.93 Å) and one longer (3.22 Å) Bi(1)-Bi(2) bond length. In the second Bi site, Bi(2) is bonded in a 11-coordinate geometry to three equivalent Ru(1), four equivalent Rh(1), and four equivalent Bi(1) atoms.
