KInSb2 crystallizes in the monoclinic Cm space group. K(1) is bonded in a single-bond geometry to one In(1) and one Sb(1) atom. The K(1)-In(1) bond length is 0.77 Å. The K(1)-Sb(1) bond length is 2.94 Å. In(1) is bonded in a single-bond geometry to one K(1) and one Sb(2) atom. The In(1)-Sb(2) bond length is 3.64 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted single-bond geometry to one K(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 3.38 Å. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to one In(1), one Sb(1), and four equivalent Sb(2) atoms. All Sb(2)-Sb(2) bond lengths are 3.45 Å.
