The material structure described by Sc3As is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded in a distorted see-saw-like geometry to four equivalent As(1) atoms. As(1) is bonded to twelve equivalent Sc(1) atoms to form a mixture of corner and face-sharing AsSc12 cuboctahedra. is represented by the CIF card [CIF]
