Which stereoisomers can this complex form?
Tap a card, then tap its group.
Find the shape first, then ask where the minority ligands can sit: side by side, opposite, or as mirror images.
Assumptions
•
Stereoisomers have the same bonds but place the ligands differently in space.
•
In a tetrahedron every corner is next to every other, so MA₂B₂ has no cis or trans form.
•
en (ethylenediamine) bites two neighbouring places; three en on an octahedron twist left or right, like a propeller.
•
Each card draws one arrangement, the minority ligands lit; a wedge comes toward you, a dashed bond goes back, and a dashed arc is one en joining two N.
