Crystal packing diagram
WebThe video describes defining selections, making a crystal packing figure, and defining colors for different chains of the molecule in a detailed manner. WebFeb 16, 2024 · In crystals, close packing refers to the efficient arrangement of constituent particles in the lattice. To further comprehend this packing, we must suppose that all particles (atoms, molecules, and ions) have the same spherical solid shape. As a result, the cubic shape of a lattice’s unit cell.
