What is coordination of the metal in Co ( en ) 2 Cl 2 ?

Step-by-step solution

The coordination is the number of bonds which are connected between the metal and ligand. The chlorine ligand is a mono dentate ligand and the ethylenediamine is a bidentate ligand. So, two ethylenediamine formed the four bonds and the two chlorine ligand formed the two bonds. Hence, the coordination of the metal in Co ( en ) 2 Cl 2 is 6 .
