U3C is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. U(1) is bonded in a distorted square co-planar geometry to four equivalent C(1) atoms. C(1) is bonded to twelve equivalent U(1) atoms to form a mixture of face and corner-sharing CU12 cuboctahedra.
U3C is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. U(1) is bonded in a distorted square co-planar geometry to four equivalent C(1) atoms. All U(1)-C(1) bond lengths are 2.86 Å. C(1) is bonded to twelve equivalent U(1) atoms to form a mixture of face and corner-sharing CU12 cuboctahedra.
