Sr Sr Al V
Sr2VAl crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 3-coordinate geometry to three equivalent V(1) and two equivalent Al(1) atoms. There are a spread of Sr(1)-V(1) bond distances ranging from 2.64-3.69 Å. There is one shorter (2.97 Å) and one longer (3.00 Å) Sr(1)-Al(1) bond length. In the second Sr site, Sr(2) is bonded in a 3-coordinate geometry to four equivalent V(1) and one Al(1) atom. There are a spread of Sr(2)-V(1) bond distances ranging from 2.97-3.96 Å. The Sr(2)-Al(1) bond length is 2.64 Å. V(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1), four equivalent Sr(2), and two equivalent Al(1) atoms. There is one shorter (3.22 Å) and one longer (3.25 Å) V(1)-Al(1) bond length. Al(1) is bonded in a 3-coordinate geometry to one Sr(2), two equivalent Sr(1), and two equivalent V(1) atoms.
