Na Al Al W
NaWAl2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a distorted single-bond geometry to one W(1), two equivalent Al(1), and two equivalent Al(2) atoms. The Na(1)-W(1) bond length is 1.43 Å. There is one shorter (2.40 Å) and one longer (2.65 Å) Na(1)-Al(1) bond length. There is one shorter (2.28 Å) and one longer (2.54 Å) Na(1)-Al(2) bond length. W(1) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Al(1), and two equivalent Al(2) atoms. There is one shorter (2.28 Å) and one longer (2.54 Å) W(1)-Al(1) bond length. There is one shorter (2.40 Å) and one longer (2.65 Å) W(1)-Al(2) bond length. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 8-coordinate geometry to two equivalent Na(1), two equivalent W(1), two equivalent Al(1), and two equivalent Al(2) atoms. Both Al(1)-Al(1) bond lengths are 2.84 Å. There is one shorter (2.10 Å) and one longer (2.75 Å) Al(1)-Al(2) bond length. In the second Al site, Al(2) is bonded in a 8-coordinate geometry to two equivalent Na(1), two equivalent W(1), two equivalent Al(1), and two equivalent Al(2) atoms. Both Al(2)-Al(2) bond lengths are 2.84 Å.
