Materials Data on CrP2 by Materials Project
CrP2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Cr6+ is bonded in a 8-coordinate geometry to eight P3- atoms. There are a spread of Cr–P bond distances ranging from 2.34–2.48 Å. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded in a 4-coordinate geometry to three equivalent Cr6+ and three equivalent P3- atoms. There are one shorter (2.19 Å) and two longer (2.47 Å) P–P bond lengths. In the second P3- site, P3- is bonded in a 5-coordinate geometry to five equivalent Cr6+ atoms.
