In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in matter. The smallest group of particles in the material that constitutes this repeating p… WebPolymorphism impacts upon society in many different ways (e.g., in agrochemicals, dyes, pharmaceuticals, etc.) as the arrangement of molecules in a crystal dictates many of the crucial physiochemical properties of these materials (e.g., solubility, bioavailability, etc.).
