PrBa crystallizes in the hexagonal P-6m2 space group. Ba(1) is bonded to six equivalent Ba(1) and six equivalent Pr(1) atoms to form BaBa6Pr6 cuboctahedra that share corners with eighteen equivalent Ba(1)Ba6Pr6 cuboctahedra, edges with six equivalent Ba(1)Ba6Pr6 cuboctahedra, edges with twelve equivalent Pr(1)Ba6Pr6 cuboctahedra, faces with eight equivalent Ba(1)Ba6Pr6 cuboctahedra, and faces with twelve equivalent Pr(1)Ba6Pr6 cuboctahedra. Pr(1) is bonded to six equivalent Ba(1) and six equivalent Pr(1) atoms to form PrBa6Pr6 cuboctahedra that share corners with eighteen equivalent Pr(1)Ba6Pr6 cuboctahedra, edges with six equivalent Pr(1)Ba6Pr6 cuboctahedra, edges with twelve equivalent Ba(1)Ba6Pr6 cuboctahedra, faces with eight equivalent Pr(1)Ba6Pr6 cuboctahedra, and faces with twelve equivalent Ba(1)Ba6Pr6 cuboctahedra.
