Question 22.5: Identifying and Drawing Geometric Isomers Draw the structure...

Identify the coordination number and the geometry around the metal.

The ethylenediamine (en) ligand is bidentate, so each occupies two coordination sites. Each Cl^- is monodentate, occupying one site. The total coordination number is 6, so this must be an octahedral complex.

Identify whether this is a cis–trans or fac–mer isomerism.

With ethylenediamine occupying four sites and Cl^- occupying two sites, it fits the general formula MA_4B_2, leading to cis–trans isomers.

Draw and label the two isomers.
