The material described by UCo2P2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 18-coordinate geometry to four equivalent Co(2), five equivalent Co(1), four equivalent P(1), and five equivalent P(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted single-bond geometry to five equivalent U(1), four equivalent Co(2), and one P(2) atom. In the second Co site, Co(2) is bonded in a distorted body-centered cubic geometry to four equivalent U(1) and four equivalent Co(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent P(2) atoms. In the second P site, P(2) is bonded in a distorted single-bond geometry to five equivalent U(1), one Co(1), and four equivalent P(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
