The crystal structure described by BSnO3 crystallizes in the monoclinic Cc space group. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(3), one O(4), and one O(5) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(6) atom. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 3-coordinate geometry to one O(3), one O(4), and one O(5) atom. In the second Sn site, Sn(2) is bonded in a trigonal bipyramidal geometry to one O(1), one O(2), one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one B(2) and one Sn(2) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one B(2) and one Sn(2) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one B(1) and one Sn(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one B(1), one Sn(1), and one Sn(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one B(1), one Sn(1), and one Sn(2) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one B(2) and one Sn(2) atom. is represented by the CIF file [CIF]
