K2SrCdSb2 crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 3-coordinate geometry to two equivalent Cd(1), one Sb(2), and two equivalent Sb(1) atoms. In the second K site, K(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Cd(1), two equivalent Sb(1), and two equivalent Sb(2) atoms. Sr(1) is bonded in a 7-coordinate geometry to four equivalent Cd(1), one Sb(1), and four equivalent Sb(2) atoms. Cd(1) is bonded in a 12-coordinate geometry to two equivalent K(1), two equivalent K(2), four equivalent Sr(1), two equivalent Sb(1), and two equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 7-coordinate geometry to two equivalent K(1), two equivalent K(2), one Sr(1), and two equivalent Cd(1) atoms. In the second Sb site, Sb(2) is bonded in a 9-coordinate geometry to one K(1), two equivalent K(2), four equivalent Sr(1), and two equivalent Cd(1) atoms.
