In the third B site, B(3) is bonded in a trigonal planar geometry to one N(2), one N(3), and one O(3) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded in a distorted bent 120 degrees geometry to one Sr(1), one Sr(2), two equivalent Sr(3), one B(1), and one B(2) atom. In the second N site, N(2) is bonded in a distorted bent 120 degrees geometry to one Sr(1), one Sr(2), one Sr(3), one B(1), and one B(3) atom. In the third N site, N(3) is bonded in a distorted bent 120 degrees geometry to one Sr(1), one Sr(2), one Sr(3), one B(2), and one B(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Sr(2), one Sr(3), two equivalent Sr(1), and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Sr(1), one Sr(2), two equivalent Sr(3), and one B(2) atom.
