The crystal structure described by ErNi4P2 crystallizes in the tetragonal P4_2/mnm space group. Er(1) is bonded in a 6-coordinate geometry to six equivalent P(1) atoms. Ni(1) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent Er(1) and six equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
