The structure described by Zr(Ni2As)2 crystallizes in the tetragonal P4_2/mnm space group. Zr(1) is bonded to twelve equivalent Ni(1) and six equivalent As(1) atoms to form distorted face-sharing ZrNi12As6 octahedra. Ni(1) is bonded in a 3-coordinate geometry to three equivalent Zr(1) and three equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to three equivalent Zr(1) and six equivalent Ni(1) atoms. is represented by the CIF file [CIF]
