Coodination Number What Different Solid State..

Coordination number used in coordination of compounds is somewhat different than that used in solid state. 

* In a coordination compound the coordination number is the number of donor atoms of ligands directly attached to metal atom or ion.

* In a solid state, the number of closest constituent atoms or ions in contact with a particular atom in the crystal lattice is called coordination number.

* In a coordination compound, coordination number depends upon nature of metal atom or ion, and its electronic configuration.

* In a solid state, the coordination number depends upon the crystalline structure of the unit cell.
