Sr(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), one O(4), one O(8), two equivalent O(1), and two equivalent O(6) atoms. Mn(1) is bonded in a 6-coordinate geometry to one O(3), one O(4), one O(5), one O(7), and two equivalent O(8) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(7) atom. In the second P site, P(2) is bonded in a tetrahedral geometry to one O(4), one O(5), one O(6), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one P(1) atom.
