This is an 3D model ofPotassium permanganate molecule structure (Realistic 3D model of Molecule KMnO4 Model).
There are 2 models in the scene 1 is the only structure and second is the detailed model having labeling and showing angles between bonds and length of bonds.
Red = Oxygen (O)
Purple = Potassium (K)
Pink = Manganese (Mn)

The model is originally created using 3ds Max 2017 and rendered with default Nvidia Mental Ray. The file includes the materials, the scene.

It is nicely detailed model.

You can use it in broadcast, film, TV, promotional video, educational training video, e-learning etc.
