KSrSb2 crystallizes in the triclinic P1 space group. K(1) is bonded in a distorted single-bond geometry to one Sb(1) and one Sb(2) atom. The K(1)-Sb(1) bond length is 3.13 Å. The K(1)-Sb(2) bond length is 1.87 Å. Sr(1) is bonded in a distorted single-bond geometry to one Sb(2) and four equivalent Sb(1) atoms. The Sr(1)-Sb(2) bond length is 2.33 Å. There are a spread of Sr(1)-Sb(1) bond distances ranging from 3.02-3.88 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to one K(1), four equivalent Sr(1), and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 2.33 Å. In the second Sb site, Sb(2) is bonded in a distorted bent 120 degrees geometry to one K(1), one Sr(1), and one Sb(1) atom.
