Materials Data on Er3AlC by Materials Project

Er3AlC is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional and consists of one methane molecule and one Er3Al framework. In the Er3Al framework, Er is bonded in a linear geometry to two equivalent Al atoms. Both Er–Al bond lengths are 2.65 Å. Al is bonded to six equivalent Er atoms to form corner-sharing AlEr6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on Er3AlC by Materials Project

Er3AlC is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Er is bonded in a linear geometry to four equivalent Al and two equivalent C atoms. All Er–Al bond lengths are 3.41 Å. Both Er–C bond lengths are 2.41 Å. Al is bonded to twelve equivalent Er atoms to form AlEr12 cuboctahedra that share corners with twelve equivalent AlEr12 cuboctahedra, faces with six equivalent AlEr12 cuboctahedra, and faces with eight equivalent CEr6 octahedra. C is bonded to six equivalent Er atoms to form CEr6 octahedra that share corners with six equivalent CEr6 octahedra and faces with eight equivalent AlEr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°.
