The crystal structure described by Dy5B3O13 crystallizes in the hexagonal P6_3/m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(4) atoms. In the second Dy site, Dy(2) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), and four equivalent O(1) atoms. B(1) is bonded in a tetrahedral geometry to one O(2), one O(4), and two equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(3) is bonded in a trigonal planar geometry to three equivalent Dy(2) atoms. In the second O site, O(4) is bonded in a 4-coordinate geometry to one Dy(2), two equivalent Dy(1), and one B(1) atom. In the third O site, O(1) is bonded in a 1-coordinate geometry to one Dy(1), two equivalent Dy(2), and one B(1) atom. In the fourth O site, O(2) is bonded in a distorted single-bond geometry to one Dy(2), two equivalent Dy(1), and one B(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
