Y2RuGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 8-coordinate geometry to two equivalent Ru(1), one Ge(1), and five equivalent Ge(2) atoms. In the second Y site, Y(2) is bonded in a 10-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Y(1), four equivalent Y(2), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to one Y(1), five equivalent Y(2), three equivalent Ru(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Y(2), five equivalent Y(1), one Ru(1), and one Ge(2) atom.
