Study Notes

Coordination Entity

A central metal atom or ion is bonded to a fixed number of ions or molecules.
The metal atom or ion is surrounded by the ions or molecules in a specific arrangement.
Examples include: [CoCl3(NH3)3], [Ni(CO)4], [PtCl2(NH3)2], [Fe(CN)6]4–, [Co(NH3)6]3+

Central Atom/Ion

The atom/ion in the center of a coordination entity is called the central atom or ion.
The central atom/ion has a fixed number of ions or groups bound to it in a specific geometric arrangement.
Examples include: [NiCl2(H2O)4], [CoCl(NH3)5]2+ and [Fe(CN)6]3–
The central atoms/ions in these examples are Ni2+, Co3+ and Fe3+, respectively.
Central atoms/ions are also referred to as Lewis acids.
