Explain the following, giving two examples:
Coordination polyhedron
उत्तर
The spatial arrangement of the ligand atoms, which are directly attached to the central atom/ion, defines a coordination polyhedron about the central atom. The most common coordination polyhedra are octahedral, square planar and tetrahedral. For example, [Co(NH3)6]3+ is octahedral, [Ni(CO)4] is tetrahedral and [PtCl4]2− is square planar.
