The material structure described by URuRhSi2 crystallizes in the tetragonal I-4m2 space group. U(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1), four equivalent Rh(1), and eight equivalent Si(1) atoms. Ru(1) is bonded to four equivalent U(1) and four equivalent Si(1) atoms to form distorted RuU4Si4 tetrahedra that share corners with four equivalent Rh(1)U4Si4 tetrahedra, corners with eight equivalent Ru(1)U4Si4 tetrahedra, edges with two equivalent Rh(1)U4Si4 tetrahedra, edges with four equivalent Ru(1)U4Si4 tetrahedra, and faces with four equivalent Rh(1)U4Si4 tetrahedra. Rh(1) is bonded to four equivalent U(1) and four equivalent Si(1) atoms to form distorted RhU4Si4 tetrahedra that share corners with four equivalent Ru(1)U4Si4 tetrahedra, corners with eight equivalent Rh(1)U4Si4 tetrahedra, edges with two equivalent Ru(1)U4Si4 tetrahedra, edges with four equivalent Rh(1)U4Si4 tetrahedra, and faces with four equivalent Ru(1)U4Si4 tetrahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent Ru(1), two equivalent Rh(1), and one Si(1) atom. is represented by the CIF card [CIF]
