The structure described by K3SnSb3 is Magnesium tetraboride-derived structured and crystallizes in the monoclinic Cm space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to one Sn(1), two equivalent Sb(1), two equivalent Sb(2), and two equivalent Sb(3) atoms. In the second K site, K(2) is bonded in a 5-coordinate geometry to two equivalent Sn(1), one Sb(3), two equivalent Sb(1), and two equivalent Sb(2) atoms. In the third K site, K(3) is bonded in a 7-coordinate geometry to one Sn(1), two equivalent Sb(1), two equivalent Sb(2), and two equivalent Sb(3) atoms. Sn(1) is bonded in a 6-coordinate geometry to one K(1), one K(3), two equivalent K(2), one Sb(3), and two equivalent Sb(2) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to two equivalent K(1), two equivalent K(2), two equivalent K(3), and two equivalent Sb(3) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to two equivalent K(1), two equivalent K(2), two equivalent K(3), and two equivalent Sn(1) atoms. In the third Sb site, Sb(3) is bonded in a 8-coordinate geometry to one K(2), two equivalent K(1), two equivalent K(3), one Sn(1), and two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
