The structure described by SnAlO3 crystallizes in the hexagonal P6_3/mmc space group. Al(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Sn(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form corner-sharing SnO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to three equivalent Sn(1) atoms. In the second O site, O(1) is bonded to three equivalent Al(1) and one Sn(1) atom to form a mixture of corner and edge-sharing OAl3Sn tetrahedra. is represented by the CIF file [CIF]
