Materials Data on Cr5As3 by Materials Project
Cr5As3 crystallizes in the orthorhombic Pnma 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 As atoms. There are a spread of Cr–As bond distances ranging from 2.40–2.67 Å. In the second Cr site, Cr is bonded in a 6-coordinate geometry to six As atoms. There are a spread of Cr–As bond distances ranging from 2.47–2.65 Å. In the third Cr site, Cr is bonded in a 5-coordinate geometry to five As atoms. There are a spread of Cr–As bond distances ranging from 2.44–2.52 Å. In the fourth Cr site, Cr is bonded in a 5-coordinate geometry to five As atoms. There are a spread of Cr–As bond distances ranging from 2.44–2.72 Å. There are two inequivalent As sites. In the first As site, As is bonded in a 8-coordinate geometry to eight Cr atoms. In the second As site, As is bonded in a 9-coordinate geometry to nine Cr atoms.
