Structure of Hexafluorido cobaltite(III) ion:
Hexafluorido cobaltite(III) ion is a complex ion composed of cobalt(III) surrounded by six fluoride ligands. The structure of this ion can be described in detail as follows:

Cobalt(III) center:
- The central cobalt atom in the ion has a +3 oxidation state, which means it has lost three electrons, resulting in a positive charge.
- Cobalt(III) typically forms six coordination bonds with surrounding ligands due to its d6 electron configuration.

Fluoride ligands:
- There are six fluoride ligands surrounding the cobalt(III) center in a octahedral geometry.
- Each fluoride ligand forms a coordination bond with the cobalt atom, resulting in a highly symmetrical structure.

Overall geometry:
- The overall geometry of the Hexafluorido cobaltite(III) ion is octahedral, with the cobalt atom at the center and the fluoride ligands at the vertices of the octahedron.
- This geometry is a result of the coordination bonds formed between the cobalt atom and the fluoride ligands.

Electronic structure:
- The Hexafluorido cobaltite(III) ion has a high symmetry due to the octahedral arrangement of ligands around the cobalt(III) center.
- The coordination bonds between the cobalt atom and the fluoride ligands result in a stable electronic structure for the ion.
In summary, the structure of the Hexafluorido cobaltite(III) ion is characterized by a cobalt(III) center surrounded by six fluoride ligands in an octahedral geometry, resulting in a highly symmetrical and stable complex ion.
