Bi Bi Ru W
WRuBi2 crystallizes in the triclinic P1 space group. W(1) is bonded in a distorted single-bond geometry to two equivalent Ru(1), one Bi(1), and one Bi(2) atom. There is one shorter (2.08 Å) and one longer (2.72 Å) W(1)-Ru(1) bond length. The W(1)-Bi(1) bond length is 1.30 Å. The W(1)-Bi(2) bond length is 2.07 Å. Ru(1) is bonded in a 6-coordinate geometry to two equivalent W(1), two equivalent Bi(1), and two equivalent Bi(2) atoms. There is one shorter (2.34 Å) and one longer (2.98 Å) Ru(1)-Bi(1) bond length. There is one shorter (2.38 Å) and one longer (2.52 Å) Ru(1)-Bi(2) bond length. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one W(1) and two equivalent Ru(1) atoms. In the second Bi site, Bi(2) is bonded in a 1-coordinate geometry to one W(1) and two equivalent Ru(1) atoms.
