In the thirteenth O site, O(13) is bonded in a distorted linear geometry to one Sr(1), one La(2), one La(3), one La(4), one Cr(2), and one Cr(4) atom. In the fourteenth O site, O(14) is bonded in a distorted linear geometry to one Sr(1), one La(2), one La(3), one La(4), one Cr(2), and one Cr(4) atom. In the fifteenth O site, O(15) is bonded in a distorted linear geometry to one Sr(1), one La(1), one La(3), one La(4), one Cr(1), and one Cr(5) atom. is represented by the CIF file [CIF]
