CaReAl2 crystallizes in the trigonal R3m space group. Ca(1) is bonded in a 10-coordinate geometry to three equivalent Re(1), three equivalent Al(2), and four equivalent Al(1) atoms. All Ca(1)-Re(1) bond lengths are 2.70 Å. All Ca(1)-Al(2) bond lengths are 2.70 Å. There are three shorter (2.74 Å) and one longer (3.20 Å) Ca(1)-Al(1) bond length. Re(1) is bonded in a single-bond geometry to three equivalent Ca(1), one Al(1), and four equivalent Al(2) atoms. The Re(1)-Al(1) bond length is 0.88 Å. There are three shorter (2.74 Å) and one longer (3.20 Å) Re(1)-Al(2) bond length. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to four equivalent Ca(1), one Re(1), and three equivalent Al(2) atoms. All Al(1)-Al(2) bond lengths are 2.70 Å. In the second Al site, Al(2) is bonded in a 10-coordinate geometry to three equivalent Ca(1), four equivalent Re(1), and three equivalent Al(1) atoms.
