Using symmetry to construct Crystals: Building Zeolite Frameworks with VESTA

Welcome to the third video in our series on crystal symmetry! In this episode, we explore how understanding symmetry can simplify complex crystal structures, making the life of a materials scientist much easier. We'll take you through the process of creating the zeolite structure of forgerite, a framework with a massive 640 atoms per unit cell, using only five atoms, a space group number, and lattice parameters. Using the powerful and free software VESTA, we'll demonstrate how these tools allow you to visualize and manipulate intricate structures with ease. From choosing the right space group to inputting atomic positions, you'll see how symmetry reduces complexity and reveals the hidden beauty in materials science. Key Topics Covered: A quick recap of symmetry elements: glide planes, mirror planes, rotations, and more. How to categorize crystals into space groups for simplification. Practical demonstration of building a complex zeolite framework using VESTA. Visualizing atomic arrangements and exploring molecular sieves through crystal channels. Sneak peek into our upcoming videos on fundamental crystal structures: FCC, BCC, and HCP. Stay tuned for more insights and practical tutorials that will deepen your understanding of crystallography.
