Crystallography is the study of crystals, their form and structure. In chemistry, we most commonly use crystallography to determine the composition and connectivity of the atoms that make up crystals. From this we can get the 3D molecular structure or the extended structure, which is useful to answer questions of coordination, connectivity, function, reactivity, biological activity, and more. Here at Notre Dame, we use crystallography to study models for the heme site in proteins, to study drug candidates, metal-organic frameworks, and the structure of carbohydrates, as well to study more basic questions of coordination chemistry.

The Molecular Structure Facility is a department resource providing single-crystal X-ray structure determinations for researchers both within the department and without. We perform hundreds of experiments each year, using three state of the art instruments. Most of the experiments are performed by students for their own research after coursework and individual training in crystallography.
