11th Canadian Chemical Crystallography Workshop (CCCW20)

This meeting is now a virtual event, 19th – 22nd May 2020

The program will consist of short lectures and demonstrations throughout the meeting. We will cover sample selection and mounting, optimizing data collection, diffraction theory, symmetry and space groups, reciprocal space, integration of data, structure solution and model building, refinement, and analyses and presentation of the derived data. Students will be solving and refining structures starting almost immediately. We will have several experienced crystallographers helping the participants. Organic, inorganic, organometallic, and solid state crystals are all fair game.

It will be impossible to go into great detail on so many topics in such a short time, so we will be relying on a lot of 3D graphics, a lot of examples, and a lot of hands on experience to get the message across. Students will take home copies of the presentations, and some data sets to work on. They will also have results from their own projects. They should be able to handle routine crystal structure analyses after the course as well as some of the trickier cases.
