The structure described by Ni3P crystallizes in the tetragonal I-4 space group. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 4-coordinate geometry to four equivalent P(1) atoms. In the second Ni site, Ni(3) is bonded in a distorted water-like geometry to two equivalent P(1) atoms. In the third Ni site, Ni(2) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to two equivalent Ni(3), three equivalent Ni(2), and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
