UCo2P2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 16-coordinate geometry to four equivalent Co(1), four equivalent Co(2), four equivalent P(1), and four equivalent P(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 5-coordinate geometry to four equivalent U(1), one P(1), and four equivalent P(2) atoms. In the second Co site, Co(2) is bonded in a 4-coordinate geometry to four equivalent U(1) and four equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 5-coordinate geometry to four equivalent U(1), one Co(1), and four equivalent Co(2) atoms. In the second P site, P(2) is bonded in a 4-coordinate geometry to four equivalent U(1) and four equivalent Co(1) atoms.
