BaSrAs2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BaSrAs2 cluster. Ba(1) is bonded in an L-shaped geometry to one As(1) and one As(2) atom. The Ba(1)-As(1) bond length is 1.88 Å. The Ba(1)-As(2) bond length is 1.66 Å. Sr(1) is bonded in an L-shaped geometry to one As(1) and one As(2) atom. The Sr(1)-As(1) bond length is 1.66 Å. The Sr(1)-As(2) bond length is 1.88 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in an L-shaped geometry to one Ba(1) and one Sr(1) atom. In the second As site, As(2) is bonded in an L-shaped geometry to one Ba(1) and one Sr(1) atom.
