Gd(RuO2)2 crystallizes in the trigonal R3m space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. All Gd(1)-Ru(1) bond lengths are 3.18 Å. In the second Gd site, Gd(2) is bonded in a 9-coordinate geometry to three equivalent Ru(2) and six equivalent Ru(1) atoms. All Gd(2)-Ru(2) bond lengths are 3.66 Å. There are three shorter (3.15 Å) and three longer (3.51 Å) Gd(2)-Ru(1) bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Gd(1), two equivalent Gd(2), and one O(1) atom. The Ru(1)-O(1) bond length is 0.85 Å. In the second Ru site, Ru(2) is bonded in a linear geometry to three equivalent Gd(2), one O(2), and one O(4) atom. The Ru(2)-O(2) bond length is 1.47 Å. The Ru(2)-O(4) bond length is 1.47 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ru(1), one O(2), and two equivalent O(1) atoms. The O(1)-O(2) bond length is 0.50 Å. Both O(1)-O(1) bond lengths are 0.29 Å. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ru(2) and three equivalent O(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one O(4) and two equivalent O(3) atoms. The O(3)-O(4) bond length is 0.50 Å. Both O(3)-O(3) bond lengths are 0.29 Å. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Ru(2) and three equivalent O(3) atoms.
