Materials Data on Sm3AlN by Materials Project
(Sm3Al)2N2 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional and consists of one ammonia molecule and one Sm3Al framework. In the Sm3Al framework, Sm is bonded in a linear geometry to two equivalent Al atoms. Both Sm–Al bond lengths are 2.73 Å. Al is bonded to six equivalent Sm atoms to form corner-sharing AlSm6 octahedra. The corner-sharing octahedral tilt angles are 0°.
