It is important to understand the crystal structure of materials to form structure-property relationships.
These relationships can help predict the behavior of crystalline materials, as well as introduce the ability to tune their properties.
Using modern software such as Olex2,[4] one can solve a crystal structure from crystallographic output files.
This relationship can be visualized as a cubic array of anions surrounding the calcium cations.
In contrast, hexagonal close-packed (hcp), are successively layered with an ABAB pattern.
