Si(1) is bonded in a tetrahedral geometry to one O(1), one O(3), one O(5), and one O(6) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Sr(2), one Sr(3), one Sr(4), and one Si(1) atom. In the second O site, O(2) is bonded to one Sr(2), one Sr(3), one Sr(4), two equivalent Sr(1), and one Pt(1) atom to form a mixture of distorted edge, corner, and face-sharing OSr5Pt octahedra. The corner-sharing octahedral tilt angles range from 0-53°. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Sr(2), two equivalent Sr(1), and one Si(1) atom. In the fourth O site, O(4) is bonded to one Sr(3), two equivalent Sr(1), two equivalent Sr(2), and one Pt(1) atom to form a mixture of distorted edge, corner, and face-sharing OSr5Pt octahedra. The corner-sharing octahedral tilt angles range from 1-53°. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Sr(1), one Sr(4), three equivalent Sr(3), and one Si(1) atom. In the sixth O site, O(6) is bonded in a 1-coordinate geometry to one Sr(3), two equivalent Sr(4), and one Si(1) atom. In the seventh O site, O(7) is bonded to one Sr(2), one Sr(3), one Sr(4), two equivalent Sr(1), and one Pt(1) atom to form a mixture of distorted edge, corner, and face-sharing OSr5Pt octahedra.
