U(RuZn10)2 crystallizes in the cubic Fd-3m space group. U(1) is bonded in a 16-coordinate geometry to four equivalent Zn(1) and twelve equivalent Zn(3) atoms. Ru(1) is bonded to six equivalent Zn(2) and six equivalent Zn(3) atoms to form RuZn12 cuboctahedra that share corners with six equivalent Ru(1)Zn12 cuboctahedra, edges with eighteen equivalent Zn(3)UZn10Ru cuboctahedra, and faces with six equivalent Zn(3)UZn10Ru cuboctahedra. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 14-coordinate geometry to two equivalent U(1) and twelve equivalent Zn(3) atoms. In the second Zn site, Zn(2) is bonded in a distorted linear geometry to two equivalent Ru(1) and six equivalent Zn(3) atoms. In the third Zn site, Zn(3) is bonded to one U(1), one Ru(1), two equivalent Zn(1), three equivalent Zn(2), and five equivalent Zn(3) atoms to form distorted ZnUZn10Ru cuboctahedra that share corners with fifteen equivalent Zn(3)UZn10Ru cuboctahedra, edges with two equivalent Zn(3)UZn10Ru cuboctahedra, edges with three equivalent Ru(1)Zn12 cuboctahedra,  a faceface with one Ru(1)Zn12 cuboctahedra, and faces with fifteen equivalent Zn(3)UZn10Ru cuboctahedra.
