PaV crystallizes in the orthorhombic Amm2 space group. Pa(1) is bonded to six equivalent Pa(1) and six equivalent V(1) atoms to form distorted PaPa6V6 cuboctahedra that share corners with eighteen equivalent Pa(1)Pa6V6 cuboctahedra, edges with six equivalent Pa(1)Pa6V6 cuboctahedra, edges with twelve equivalent V(1)Pa6V6 cuboctahedra, faces with eight equivalent Pa(1)Pa6V6 cuboctahedra, and faces with twelve equivalent V(1)Pa6V6 cuboctahedra. V(1) is bonded to six equivalent Pa(1) and six equivalent V(1) atoms to form distorted VPa6V6 cuboctahedra that share corners with eighteen equivalent V(1)Pa6V6 cuboctahedra, edges with six equivalent V(1)Pa6V6 cuboctahedra, edges with twelve equivalent Pa(1)Pa6V6 cuboctahedra, faces with eight equivalent V(1)Pa6V6 cuboctahedra, and faces with twelve equivalent Pa(1)Pa6V6 cuboctahedra.
