NdCu3Ru4O12 crystallizes in the cubic Im-3 space group. Nd(1) is bonded to twelve equivalent O(1) atoms to form NdO12 cuboctahedra that share faces with eight equivalent Ru(1)O6 octahedra. Ru(1) is bonded to six equivalent O(1) atoms to form RuO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra and faces with two equivalent Nd(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 42°. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to one Nd(1), two equivalent Ru(1), and one Cu(1) atom to form a mixture of distorted corner and edge-sharing ONdCuRu2 tetrahedra.
