Hf Al W
HfWAl crystallizes in the triclinic P1 space group. Hf(1) is bonded in a 4-coordinate geometry to two equivalent W(1) and two equivalent Al(1) atoms. There is one shorter (2.66 Å) and one longer (2.86 Å) Hf(1)-W(1) bond length. There is one shorter (1.65 Å) and one longer (2.31 Å) Hf(1)-Al(1) bond length. W(1) is bonded in a 1-coordinate geometry to two equivalent Hf(1) and one Al(1) atom. The W(1)-Al(1) bond length is 1.82 Å. Al(1) is bonded in a 2-coordinate geometry to two equivalent Hf(1) and one W(1) atom.
