CoNi2P crystallizes in the monoclinic Cm space group. Co(1) is bonded in a 10-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), and two equivalent P(1) atoms. There are a spread of Co(1)-Ni(1) bond distances ranging from 2.47-2.63 Å. There are a spread of Co(1)-Ni(2) bond distances ranging from 2.47-2.63 Å. There is one shorter (2.49 Å) and one longer (2.51 Å) Co(1)-P(1) bond length. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to four equivalent Co(1), one Ni(2), and four equivalent P(1) atoms. The Ni(1)-Ni(2) bond length is 2.09 Å. There are a spread of Ni(1)-P(1) bond distances ranging from 2.24-2.42 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to four equivalent Co(1), one Ni(1), and four equivalent P(1) atoms. There are a spread of Ni(2)-P(1) bond distances ranging from 2.25-2.43 Å. P(1) is bonded in a 10-coordinate geometry to two equivalent Co(1), four equivalent Ni(1), and four equivalent Ni(2) atoms.
