The structure described by Eu3(BO3)2F3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(3), three equivalent O(2), one F(1), and one F(2) atom. In the second Eu site, Eu(2) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(3), one F(1), and four equivalent F(2) atoms. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(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 Eu(2), two equivalent Eu(1), and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Eu(1) and one B(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Eu(2), two equivalent Eu(1), and one B(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to one Eu(2) and two equivalent Eu(1) atoms. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Eu(1) and two equivalent Eu(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
