Zr6Ru7Ga16 crystallizes in the cubic Fm-3m space group. Zr(1) is bonded in a 12-coordinate geometry to four equivalent Ru(2), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded to four equivalent Zr(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted face and corner-sharing RuZr4Ga8 cuboctahedra. In the second Ru site, Ru(1) is bonded in a body-centered cubic geometry to eight equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 6-coordinate geometry to three equivalent Zr(1) and three equivalent Ru(2) atoms. In the second Ga site, Ga(1) is bonded in a 7-coordinate geometry to three equivalent Zr(1), one Ru(1), and three equivalent Ru(2) atoms.
