The structure described by Eu3BWO9 crystallizes in the hexagonal P6_3 space group. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. W(1) is bonded in a distorted octahedral geometry to three equivalent O(1) and three equivalent O(2) atoms. B(1) is bonded in a trigonal planar geometry to three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Eu(1) and one W(1) atom. In the second O site, O(2) is bonded to three equivalent Eu(1) and one W(1) atom to form a mixture of distorted edge and corner-sharing OEu3W tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Eu(1) and one B(1) atom. is represented by the CIF card [CIF]
