The crystal structure described by Re3As7 crystallizes in the cubic Im-3m space group. Re(1) is bonded in a 8-coordinate geometry to four equivalent As(1) and four equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 4-coordinate geometry to three equivalent Re(1) and one As(2) atom. In the second As site, As(1) is bonded in a 4-coordinate geometry to four equivalent Re(1) atoms. is represented by the CIF card [CIF]
