The crystal structure described by Eu3B2O6 crystallizes in the trigonal R-3c space group. Eu(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. B(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to four equivalent Eu(1) and one B(1) atom. is represented by the CIF card [CIF]
