The compound described by Eu2BN2Br crystallizes in the trigonal R-3m space group. Eu(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent N(1) and three equivalent Br(1) atoms. B(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to three equivalent Eu(1) and one B(1) atom to form NEu3B tetrahedra that share corners with three equivalent Br(1)Eu6 octahedra, corners with seven equivalent N(1)Eu3B tetrahedra, and edges with three equivalent Br(1)Eu6 octahedra. The corner-sharing octahedral tilt angles are 25°. Br(1) is bonded to six equivalent Eu(1) atoms to form distorted BrEu6 octahedra that share corners with six equivalent N(1)Eu3B tetrahedra, edges with six equivalent Br(1)Eu6 octahedra, and edges with six equivalent N(1)Eu3B tetrahedra. is represented by the CIF card [CIF]
