(1) Coordination Entity: Coordination entity is a charged entity having positive or negative charge in which the central atom is surrounded by molecules which may be neutral/negatively charged called Ligands
Examples:
i. Cationic Complexes: [Cu (H2O)6]2+, [Al (H2O)6]3+
ii. Anionic Complexes: [CuCl4]2-, [Al (H2O)2 (OH)4]-
iii. Neutral Complexes: [Co (NH3)4 Cl2], [Ni (CO)4]
(2) Ligands: Ligands are the neutral or negatively charged entities surrounding the central metal atom of the coordination complex which possesses at least one unshared pair of electrons
Example: F-, Cl-, Br-, I-, H20, and NH3
(3) Coordination Number: Coordina
