An Example using the [Tris(σ-diaminobenzene)Rhenium(VII)]+ Ion
Potenially useful Viewing Commands:




The [Re(σ-diaminobenzene)3]+ ion is a tris chelate with a slightly different structure than we have seen before. More Info/Reference
1. Determine the symmetry operations for the molecule and assign it to a point group. (Note there are hints in this page!)
2. Is this ion chiral? Why or Why Not?

Move the molecule with your mouse to look for various elements of symmetry
The following buttons might help you determine if you have C3 or C2 symmetry
Test for a C3:
Test for a C2:
