B. The Symmetry Properties of Metal Tris Chelates 1. With Symmetrical Chelating Ligands: Molecules of D3 Symmetry a. The C3 Operations Example with one isomer of the Co(H2NCH2CH2NH2)33+ Ion More Information This molecular ion has D3 symmetry and the following symmetry operations: E, C3, C32, and 3 C2's a. First we will animate the C3 Operations Useful commands for viewing the operations: Animation of the C3 Operations: 1. The C3 2. The C32 3. The The C33 = E Notice the C33 is the same as the identity (E) and is therefore not unique and is therefore NOT listed as a symmetry operation for this molecular ion. b. Next we will look at the C2 Operations
