The crystal structure described by K2SnOCl4 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to one O(1), two equivalent Cl(1), two equivalent Cl(3), and three equivalent Cl(2) atoms. Sn(1) is bonded in a distorted trigonal bipyramidal geometry to one O(1), one Cl(1), one Cl(3), and two equivalent Cl(2) atoms. O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one Sn(1) atom. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Sn(1) atom. In the second Cl site, Cl(2) is bonded in a 4-coordinate geometry to three equivalent K(1) and one Sn(1) atom. In the third Cl site, Cl(3) is bonded to four equivalent K(1) and one Sn(1) atom to form distorted corner-sharing ClK4Sn square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
