Question
**Determine the point group for the following molecule:**

The diagram depicts a chemical structure with a central zinc (Zn) atom bonded to three cyanide (CN) groups. Each CN group is represented with a triple bond between the carbon (C) and nitrogen (N) atoms, with the nitrogens facing outward from the zinc. The entire complex carries a 2- charge.

### Diagram Explanation:
- The central atom is Zn (zinc).
- Three CN ligands are bonded to the zinc.
- The structure suggests trigonal planar geometry around the central zinc atom, with 120-degree angles between the bonds.

### Analyzing the Point Group:
- The molecule likely belongs to the D3h point group due to its trigonal planar shape and symmetrical nature. This point group is characterized by:
  - One C3 principal axis (threefold rotational symmetry).
  - Three C2 perpendicular axes.
  - Horizontal reflection planes (σh).
  - Vertical reflection planes (σv).
