Ge Ge Ru W
WRuGe2 crystallizes in the monoclinic Cm space group. W(1) is bonded in a 4-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. The W(1)-Ge(2) bond length is 3.16 Å. There are a spread of W(1)-Ge(1) bond distances ranging from 1.84-2.26 Å. Ru(1) is bonded in a 1-coordinate geometry to one Ge(1) and four equivalent Ge(2) atoms. The Ru(1)-Ge(1) bond length is 2.58 Å. There are a spread of Ru(1)-Ge(2) bond distances ranging from 3.03-3.30 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent W(1) and one Ru(1) atom to form a mixture of distorted edge and corner-sharing GeRuW4 square pyramids. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one W(1), four equivalent Ru(1), and four equivalent Ge(2) atoms. All Ge(2)-Ge(2) bond lengths are 2.90 Å.
