Materials Data on Re3As7 by Materials Project
Re3As7 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Re+4.33+ is bonded in a 8-coordinate geometry to eight As+1.86- atoms. There are four shorter (2.59 Å) and four longer (2.63 Å) Re–As bond lengths. There are two inequivalent As+1.86- sites. In the first As+1.86- site, As+1.86- is bonded in a 4-coordinate geometry to three equivalent Re+4.33+ and one As+1.86- atom. The As–As bond length is 2.58 Å. In the second As+1.86- site, As+1.86- is bonded in a 8-coordinate geometry to four equivalent Re+4.33+ atoms.
