The crystal structure described by Sr7B3SiNO13 crystallizes in the hexagonal P6_3 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to two equivalent N(1), one O(2), one O(4), two equivalent O(3), and three equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded in a 7-coordinate geometry to one O(5), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the third Sr site, Sr(3) is bonded in a 10-coordinate geometry to one O(5), three equivalent O(2), three equivalent O(3), and three equivalent O(4) atoms. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. Si(1) is bonded in a tetrahedral geometry to one O(5) and three equivalent O(4) atoms. N(1) is bonded to six equivalent Sr(1) atoms to form distorted face-sharing NSr6 octahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three 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(3), two equivalent Sr(2), and one B(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Sr(3), two equivalent Sr(1), two equivalent Sr(2), and one B(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Sr(1), one Sr(3), two equivalent Sr(2), and one Si(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal bipyramidal geometry to one Sr(3), three equivalent Sr(2), and one Si(1) atom. is represented by the CIF card [CIF]
