Materials Data on AlSnO3 by Materials Project

SnAlO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional and consists of one aluminum molecule and one SnO3 framework. In the SnO3 framework, Sn3+ is bonded to six equivalent O2- atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sn–O bond lengths are 2.02 Å. O2- is bonded in a linear geometry to two equivalent Sn3+ atoms.

Materials Data on AlSnO3 by Materials Project

SnAlO3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Al3+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Al–O bond lengths are 2.16 Å. Sn3+ is bonded to five O2- atoms to form corner-sharing SnO5 trigonal bipyramids. There are three shorter (1.98 Å) and two longer (2.26 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Sn3+ atoms. In the second O2- site, O2- is bonded to three equivalent Al3+ and one Sn3+ atom to form a mixture of edge and corner-sharing OAl3Sn tetrahedra.
