Materials Data on Er(Ni2P)2 by Materials Project
ErNi4P2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Er is bonded in a 6-coordinate geometry to six equivalent P atoms. There are two shorter (2.80 Å) and four longer (2.83 Å) Er–P bond lengths. Ni is bonded in a 3-coordinate geometry to three equivalent P atoms. There are two shorter (2.30 Å) and one longer (2.31 Å) Ni–P bond lengths. P is bonded in a 9-coordinate geometry to three equivalent Er and six equivalent Ni atoms.
