How to use this simulation

Choose a formula type such as [MA₄B₂] or [M(AA)₃].
Step through each isomer and rotate it.
For chiral isomers, turn on “Show the mirror image”.

What to notice

cis = same ligands next to each other; trans = opposite.
[Co(en)₃]³⁺ has Δ and Λ forms — mirror images, like hands.
