Materials Data on Al4W by Materials Project
Al4W crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent W sites. In the first W site, W is bonded in a 10-coordinate geometry to ten Al atoms. There are a spread of W–Al bond distances ranging from 2.56–2.83 Å. In the second W site, W is bonded in a 11-coordinate geometry to eleven Al atoms. There are a spread of W–Al bond distances ranging from 2.55–2.85 Å. There are seven inequivalent Al sites. In the first Al site, Al is bonded in a 4-coordinate geometry to four W atoms. In the second Al site, Al is bonded in a 1-coordinate geometry to four W atoms. In the third Al site, Al is bonded in a distorted linear geometry to two W atoms. In the fourth Al site, Al is bonded in a 3-coordinate geometry to three W atoms. In the fifth Al site, Al is bonded in a 3-coordinate geometry to three W atoms. In the sixth Al site, Al is bonded in a 2-coordinate geometry to two equivalent W atoms. In the seventh Al site, Al is bonded in a 2-coordinate geometry to two equivalent W atoms.
