Materials Data on Sc3AlC by Materials Project
AlCSc3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sc is bonded in a linear geometry to four equivalent Al and two equivalent C atoms. All Sc–Al bond lengths are 3.19 Å. Both Sc–C bond lengths are 2.26 Å. Al is bonded to twelve equivalent Sc atoms to form AlSc12 cuboctahedra that share corners with twelve equivalent AlSc12 cuboctahedra, faces with six equivalent AlSc12 cuboctahedra, and faces with eight equivalent CSc6 octahedra. C is bonded to six equivalent Sc atoms to form CSc6 octahedra that share corners with six equivalent CSc6 octahedra and faces with eight equivalent AlSc12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°.
