Zn Zn Ru Ru W
WRu2Zn2 crystallizes in the monoclinic Cm space group. W(1) is bonded in a 5-coordinate geometry to one Ru(1) and four equivalent Zn(1) atoms. The W(1)-Ru(1) bond length is 1.58 Å. There are two shorter (2.15 Å) and two longer (2.33 Å) W(1)-Zn(1) bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to one W(1) and one Ru(2) atom. The Ru(1)-Ru(2) bond length is 2.07 Å. In the second Ru site, Ru(2) is bonded in a 3-coordinate geometry to one Ru(1) and two equivalent Zn(1) atoms. Both Ru(2)-Zn(1) bond lengths are 2.11 Å. Zn(1) is bonded in a 4-coordinate geometry to two equivalent W(1), one Ru(2), and one Zn(1) atom. The Zn(1)-Zn(1) bond length is 1.65 Å.
