5. What is the Symmetry of The [Fe(TRENCAM)]3- Ion?


Potentially useful viewing commands:





The [FeTRENCAM]3- Ion is yet another tris chelate with a slightly different structure than we have seen before. More Information
The three chelate rings are capped with a tris(aminoethane)amine molecular subunit creating a single hexadenate ligand that wraps around the Fe(III) metal center.
1. Determine the symmetry operations for this ion and assign it to a point group.
2. Is this ion chiral? If so, is this a Λ or a Δ Isomer? If it is not chiral, give an explanation based on symmetry arguments.
