The compound described by Al4W crystallizes in the monoclinic Cm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 10-coordinate geometry to two equivalent Al(1), two equivalent Al(2), two equivalent Al(3), two equivalent Al(4), and two equivalent Al(5) atoms. In the second W site, W(2) is bonded in a 11-coordinate geometry to one Al(1), one Al(2), one Al(3), two equivalent Al(4), two equivalent Al(5), two equivalent Al(6), and two equivalent Al(7) atoms. There are seven inequivalent Al sites. In the first Al site, Al(1) is bonded in a 4-coordinate geometry to two equivalent W(1) and two equivalent W(2) atoms. In the second Al site, Al(2) is bonded in a 4-coordinate geometry to two equivalent W(1) and two equivalent W(2) atoms. In the third Al site, Al(3) is bonded in a distorted linear geometry to one W(1) and one W(2) atom. In the fourth Al site, Al(4) is bonded in a 3-coordinate geometry to one W(1) and two equivalent W(2) atoms. In the fifth Al site, Al(5) is bonded in a 3-coordinate geometry to one W(1) and two equivalent W(2) atoms. In the sixth Al site, Al(6) is bonded in a 2-coordinate geometry to two equivalent W(2) atoms. In the seventh Al site, Al(7) is bonded in a 2-coordinate geometry to two equivalent W(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
