The material described by Al3Ru2 crystallizes in the trigonal P-3m1 space group. Ru(1) is bonded in a body-centered cubic geometry to three equivalent Al(1) and five equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 6-coordinate geometry to six equivalent Ru(1) atoms. In the second Al site, Al(2) is bonded in a 5-coordinate geometry to five equivalent Ru(1) atoms. is represented by the CIF file [CIF]
