The crystal structure described by Eu2PBr is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Eu(1) is bonded to three equivalent P(1) and three equivalent Br(1) atoms to form a mixture of corner and edge-sharing EuP3Br3 octahedra. The corner-sharing octahedra are not tilted. P(1) is bonded to six equivalent Eu(1) atoms to form PEu6 octahedra that share corners with six equivalent Br(1)Eu6 octahedra, edges with six equivalent P(1)Eu6 octahedra, and edges with six equivalent Br(1)Eu6 octahedra. The corner-sharing octahedral tilt angles are 8°. Br(1) is bonded to six equivalent Eu(1) atoms to form BrEu6 octahedra that share corners with six equivalent P(1)Eu6 octahedra, edges with six equivalent P(1)Eu6 octahedra, and edges with six equivalent Br(1)Eu6 octahedra. The corner-sharing octahedral tilt angles are 8°. is represented by the Crystallographic Information File (CIF) [CIF]
