Detailed explanation-1: -coordination number, the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbours in a complex or coordination compound or in a crystal.
Detailed explanation-2: -Ligands: Ligands are ions or molecules attached to the central atom or ion of the coordination entity. Simple ions such as Cl–, small molecules such as H2O or NH3, larger molecules such as H2 NCH2CH2NH2 or N(CH2 CH2 NH2)3, and even macromolecules such as proteins are examples of ligands.
Detailed explanation-3: -The Steric number is the total number of atoms directly bonded to a central metal atom and the number of lone pairs attached. Steric number plays an essential role in VSEPR (Valence Shell Electron Pair Repulsion) theory in assessing the molecular geometry.
