Al Al B W
WAl2B crystallizes in the triclinic P1 space group. W(1) is bonded in a 2-coordinate geometry to one Al(2), four equivalent Al(1), and two equivalent B(1) atoms. The W(1)-Al(2) bond length is 2.33 Å. There are a spread of W(1)-Al(1) bond distances ranging from 2.20-2.66 Å. There is one shorter (2.90 Å) and one longer (2.92 Å) W(1)-B(1) bond length. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 6-coordinate geometry to four equivalent W(1) and two equivalent Al(2) atoms. There is one shorter (1.76 Å) and one longer (1.79 Å) Al(1)-Al(2) bond length. In the second Al site, Al(2) is bonded in a 5-coordinate geometry to one W(1), two equivalent Al(1), and two equivalent B(1) atoms. There is one shorter (2.41 Å) and one longer (2.43 Å) Al(2)-B(1) bond length. B(1) is bonded in a 4-coordinate geometry to two equivalent W(1) and two equivalent Al(2) atoms.
