The compound described by NaAs is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. Na(1) is bonded to four equivalent Na(1) and eight equivalent As(1) atoms to form distorted NaNa4As8 cuboctahedra that share corners with twelve equivalent Na(1)Na4As8 cuboctahedra, corners with sixteen equivalent As(1)Na8 cuboctahedra, edges with eight equivalent Na(1)Na4As8 cuboctahedra, edges with eight equivalent As(1)Na8 cuboctahedra, and faces with ten equivalent Na(1)Na4As8 cuboctahedra. As(1) is bonded to eight equivalent Na(1) atoms to form distorted AsNa8 cuboctahedra that share corners with eight equivalent As(1)Na8 cuboctahedra, corners with sixteen equivalent Na(1)Na4As8 cuboctahedra, edges with eight equivalent Na(1)Na4As8 cuboctahedra, edges with twelve equivalent As(1)Na8 cuboctahedra, and faces with six equivalent As(1)Na8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
