Ru2Ge3 crystallizes in the orthorhombic Pcc2 space group. There are four inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four Ge(2,2) atoms. In the second Ru site, Ru(2) is bonded in a 8-coordinate geometry to four equivalent Ge(1) and four Ge(2,2) atoms. In the third Ru site, Ru(1) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four Ge(2,2) atoms. In the fourth Ru site, Ru(3) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four Ge(2,2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to one Ru(3); two Ru(1,1); and two equivalent Ru(2) atoms. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to one Ru(2); one Ru(3); and two Ru(1,1) atoms. In the third Ge site, Ge(2) is bonded in a 4-coordinate geometry to one Ru(2); one Ru(3); and two Ru(1,1) atoms.
Ru2Ge3 crystallizes in the orthorhombic Pcc2 space group. There are four inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four Ge(2,2) atoms. Both Ru(1)-Ge(1) bond lengths are 2.42 Å. There are two shorter (2.46 Å) and two longer (2.60 Å) Ru(1)-Ge(2,2) bond lengths. In the second Ru site, Ru(2) is bonded in a 8-coordinate geometry to four equivalent Ge(1) and four Ge(2,2) atoms. There are two shorter (2.71 Å) and two longer (2.72 Å) Ru(2)-Ge(1) bond lengths. All Ru(2)-Ge(2,2) bond lengths are 2.49 Å. In the third Ru site, Ru(1) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four Ge(2,2) atoms. Both Ru(1)-Ge(1) bond lengths are 2.43 Å. There are two shorter (2.47 Å) and two longer (2.60 Å) Ru(1)-Ge(2,2) bond lengths. In the fourth Ru site, Ru(3) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four Ge(2,2) atoms. Both Ru(3)-Ge(1) bond lengths are 2.65 Å. All Ru(3)-Ge(2,2) bond lengths are 2.39 Å. There are three inequivalent Ge sites.
