The compound described by In3As is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. In(1) is bonded to eight equivalent In(1) and four equivalent As(1) atoms to form distorted InIn8As4 cuboctahedra that share corners with twelve equivalent In(1)In8As4 cuboctahedra, edges with eight equivalent As(1)In12 cuboctahedra, edges with sixteen equivalent In(1)In8As4 cuboctahedra, faces with four equivalent As(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)In8As4 cuboctahedra. As(1) is bonded to twelve equivalent In(1) atoms to form AsIn12 cuboctahedra that share corners with twelve equivalent As(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)In8As4 cuboctahedra, faces with six equivalent As(1)In12 cuboctahedra, and faces with twelve equivalent In(1)In8As4 cuboctahedra. is represented by the CIF file [CIF]
