KCdOCl3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to two equivalent O(1), one Cl(3), two equivalent Cl(2), and four equivalent Cl(1) atoms. Cd(1) is bonded to one Cl(1), two equivalent Cl(2), and three equivalent Cl(3) atoms to form edge-sharing CdCl6 octahedra. O(1) is bonded in an L-shaped geometry to two equivalent K(1) atoms. 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 Cd(1) atom. In the second Cl site, Cl(2) is bonded to two equivalent K(1) and two equivalent Cd(1) atoms to form distorted corner-sharing ClK2Cd2 trigonal pyramids. In the third Cl site, Cl(3) is bonded in a distorted rectangular see-saw-like geometry to one K(1) and three equivalent Cd(1) atoms.
KCdOCl3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to two equivalent O(1), one Cl(3), two equivalent Cl(2), and four equivalent Cl(1) atoms. Both K(1)-O(1) bond lengths are 3.03 Å. The K(1)-Cl(3) bond length is 3.55 Å. There is one shorter (3.12 Å) and one longer (3.60 Å) K(1)-Cl(2) bond length. There are two shorter (3.11 Å) and two longer (3.16 Å) K(1)-Cl(1) bond lengths. Cd(1) is bonded to one Cl(1), two equivalent Cl(2), and three equivalent Cl(3) atoms to form edge-sharing CdCl6 octahedra. The Cd(1)-Cl(1) bond length is 2.56 Å. Both Cd(1)-Cl(2) bond lengths are 2.66 Å. There is one shorter (2.69 Å) and two longer (2.76 Å) Cd(1)-Cl(3) bond lengths. O(1) is bonded in an L-shaped geometry to two equivalent K(1) atoms.
