Ru2Ge3 crystallizes in the orthorhombic Pbcn space group. There are three inequivalent Ru sites. In the first Ru site, Ru(3) is bonded in a 7-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), and three equivalent Ge(2) atoms. In the second Ru site, Ru(1) is bonded to two equivalent Ge(3) and four equivalent Ge(1) atoms to form distorted edge-sharing RuGe6 octahedra. In the third Ru site, Ru(2) is bonded in a 8-coordinate geometry to four equivalent Ge(2) and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to two equivalent Ru(1) and two equivalent Ru(3) atoms. In the second Ge site, Ge(2) is bonded in a 5-coordinate geometry to two equivalent Ru(2) and three equivalent Ru(3) atoms. In the third Ge site, Ge(3) is bonded in a 4-coordinate geometry to one Ru(1), two equivalent Ru(2), and two equivalent Ru(3) atoms.

In the first Ru site, Ru(3) is bonded in a 7-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), and three equivalent Ge(2) atoms. Both Ru(3)-Ge(1) bond lengths are 2.51 Å. There is one shorter (2.56 Å) and one longer (2.57 Å) Ru(3)-Ge(3) bond length. There are a spread of Ru(3)-Ge(2) bond distances ranging from 2.42-2.64 Å. In the second Ru site, Ru(1) is bonded to two equivalent Ge(3) and four equivalent Ge(1) atoms to form distorted edge-sharing RuGe6 octahedra. Both Ru(1)-Ge(3) bond lengths are 2.44 Å. There are two shorter (2.40 Å) and two longer (2.53 Å) Ru(1)-Ge(1) bond lengths. In the third Ru site, Ru(2) is bonded in a 8-coordinate geometry to four equivalent Ge(2) and four equivalent Ge(3) atoms. There are two shorter (2.44 Å) and two longer (2.80 Å) Ru(2)-Ge(2) bond lengths. There are two shorter (2.46 Å) and two longer (2.80 Å) Ru(2)-Ge(3) bond lengths.
