1. Each structural unit of vanadinite contains a chlorine ion surrounded by six divalent lead ions at the corners of a regular octahedron, with one of the lead ions provided by an adjoining vanadinite molecule.

2. Vanadinite when containing a high amount of the arsenic impurity is known as endlichite.

3. Common impurities of vanadinite include phosphorus, arsenic and calcium, where these may act as an isomorphic substitute for vanadium.

4. Mimetite group minerals are a group of isomorphic series minerals with hexagonal system, which include mimetite, vanadinite and pyromorphite .

5. The extended Apatite supergroup describes additional minerals such as Pyromorphite, Mimetite, and Vanadinite, but these are described individually in this guide.

7. The unit cell of vanadinite is composed of two of its molecules and has the dimensions a = 10.331 Å and c = 7.343 Å), where a is the length of each side of the hexagon and c is the height of the prism.
