Sc Sc Al W
Sc2WAl crystallizes in the triclinic P1 space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 4-coordinate geometry to two equivalent W(1) and four equivalent Al(1) atoms. There is one shorter (2.78 Å) and one longer (3.00 Å) Sc(1)-W(1) bond length. There are a spread of Sc(1)-Al(1) bond distances ranging from 2.38-3.33 Å. In the second Sc site, Sc(2) is bonded in a 2-coordinate geometry to two equivalent W(1) and four equivalent Al(1) atoms. There is one shorter (2.34 Å) and one longer (2.62 Å) Sc(2)-W(1) bond length. There are a spread of Sc(2)-Al(1) bond distances ranging from 2.89-3.40 Å. W(1) is bonded in a 1-coordinate geometry to two equivalent Sc(1), two equivalent Sc(2), and one Al(1) atom. The W(1)-Al(1) bond length is 3.23 Å. Al(1) is bonded in a 11-coordinate geometry to four equivalent Sc(1), four equivalent Sc(2), one W(1), and two equivalent Al(1) atoms. Both Al(1)-Al(1) bond lengths are 2.95 Å.
