Materials Data on U(CoP)2 by Materials Project

Abstract

UCo2P2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. U3+ is bonded in a 4-coordinate geometry to four equivalent Co+1.50+ and nine P3- atoms. All U–Co bond lengths are 2.78 Å. There are a spread of U–P bond distances ranging from 3.15–3.34 Å. There are two inequivalent Co+1.50+ sites. In the first Co+1.50+ site, Co+1.50+ is bonded in a single-bond geometry to one P3- atom. The Co–P bond length is 2.07 Å. In the second Co+1.50+ site, Co+1.50+ is bonded in a 4-coordinate geometry to four equivalent U3+ atoms. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded in a 8-coordinate geometry to four equivalent U3+ and four equivalent P3- atoms. All P–P bond lengths are 2.26 Å. In the second P3- site, P3- is bonded in a distorted single-bond geometry to five equivalent U3+, one Co+1.50+, and four equivalent P3- atoms.
