Na3CoC2O6Cl crystallizes in the cubic Fd-3 space group. Na(1) is bonded in a 6-coordinate geometry to four equivalent O(1) and two equivalent Cl(1) atoms. Co(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Co(1), and one C(1) atom. Cl(1) is bonded to six equivalent Na(1) atoms to form distorted corner-sharing ClNa6 octahedra. The corner-sharing octahedral tilt angles are 58°.
Na3CoC2O6Cl crystallizes in the cubic Fd-3 space group. Na(1) is bonded in a 6-coordinate geometry to four equivalent O(1) and two equivalent Cl(1) atoms. There are two shorter (2.39 Å) and two longer (2.45 Å) Na(1)-O(1) bond lengths. Both Na(1)-Cl(1) bond lengths are 2.85 Å. Co(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. All Co(1)-O(1) bond lengths are 2.12 Å. C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. All C(1)-O(1) bond lengths are 1.30 Å. O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Co(1), and one C(1) atom. Cl(1) is bonded to six equivalent Na(1) atoms to form distorted corner-sharing ClNa6 octahedra. The corner-sharing octahedral tilt angles are 58°.
