Crystal Structure
Crystal structure is the precise, repeating three-dimensional arrangement of atoms, ions, or molecules within a crystalline solid, defined by a unit cell that tiles space through regular translation and encoded in one of 230 space groups.
Overview
The arrangement of atoms determines a material's physical and chemical behavior — electrical conductivity, optical transparency, mechanical hardness, and magnetic response all emerge directly from atomic packing and bonding. X-ray diffraction, pioneered by Max von Laue and the Braggs in the early twentieth century, transformed crystal structure determination into a rigorous, predictive science.
Why it matters
Understanding crystal structure was the essential breakthrough that enabled the discovery of DNA's double helix from X-ray diffraction data, illustrating how a tool from physics and chemistry became foundational to molecular biology. The concept also shaped materials engineering: the dramatic property differences between graphite and diamond, or between pharmaceutical drug polymorphs, all trace back to structural arrangement.
