The structure described by LuRuGe2 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 12-coordinate geometry to one Ru(2), three equivalent Ru(1), one Ge(4), one Ge(5), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Lu site, Lu(2) is bonded in a 7-coordinate geometry to four equivalent Ru(1), two equivalent Ge(1), two equivalent Ge(3), and three equivalent Ge(5) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 12-coordinate geometry to two equivalent Lu(2), three equivalent Lu(1), one Ru(2), one Ge(2), one Ge(3), one Ge(4), one Ge(5), and two equivalent Ge(1) atoms. In the second Ru site, Ru(2) is bonded in a 6-coordinate geometry to two equivalent Lu(1), two equivalent Ru(1), two equivalent Ge(1), two equivalent Ge(4), and two equivalent Ge(5) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(5) is bonded in a 9-coordinate geometry to two equivalent Lu(1), three equivalent Lu(2), two equivalent Ru(1), and two equivalent Ru(2) atoms. In the second Ge site, Ge(1) is bonded in a 7-coordinate geometry to one Lu(2), two equivalent Lu(1), one Ru(2), two equivalent Ru(1), and one Ge(1) atom. In the third Ge site, Ge(2) is bonded in a 7-coordinate geometry to four equivalent Lu(1), two equivalent Ru(1), and one Ge(2) atom. In the fourth Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Lu(2), four equivalent Lu(1), two equivalent Ru(1), and one Ge(3) atom.
