Materials Data on Cr12P7 by Materials Project

Abstract

Cr12P7 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are four inequivalent Cr sites. In the first Cr site, Cr is bonded in a 5-coordinate geometry to five P atoms. There are a spread of Cr–P bond distances ranging from 2.33–2.37 Å. In the second Cr site, Cr is bonded in a 4-coordinate geometry to four P atoms. There are a spread of Cr–P bond distances ranging from 2.26–2.42 Å. In the third Cr site, Cr is bonded in a 5-coordinate geometry to five P atoms. There are a spread of Cr–P bond distances ranging from 2.33–2.49 Å. In the fourth Cr site, Cr is bonded in a 5-coordinate geometry to five P atoms. There are a spread of Cr–P bond distances ranging from 2.40–2.54 Å. There are three inequivalent P sites. In the first P site, P is bonded in a 9-coordinate geometry to nine Cr atoms. In the second P site, P is bonded in a 8-coordinate geometry to eight Cr atoms. In the third P site, P is bonded in a 8-coordinate geometry to eight Cr atoms.
