Ba2PCl is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Ba(1) is bonded to three equivalent P(1) and three equivalent Cl(1) atoms to form a mixture of corner and edge-sharing BaP3Cl3 octahedra. The corner-sharing octahedra are not tilted. P(1) is bonded to six equivalent Ba(1) atoms to form PBa6 octahedra that share corners with six equivalent Cl(1)Ba6 octahedra, edges with six equivalent P(1)Ba6 octahedra, and edges with six equivalent Cl(1)Ba6 octahedra. The corner-sharing octahedral tilt angles are 6°. Cl(1) is bonded to six equivalent Ba(1) atoms to form ClBa6 octahedra that share corners with six equivalent P(1)Ba6 octahedra, edges with six equivalent P(1)Ba6 octahedra, and edges with six equivalent Cl(1)Ba6 octahedra. The corner-sharing octahedral tilt angles are 6°.
