What kind of the machine you used?🤔

Sure. Glad that you find them useful 😀 Best of luck with the Duffy proposal!

Connecting Key Concepts with Student Experience: Introducing Small-Molecule Crystallography to Chemistry Undergraduates Using a Flexible Laboratory Module A strategy for incorporating crystallography laboratory practice into various experimental chemistry courses for undergraduates is described. The flexible approach that relates key concepts to hands-on activities allows students to draw an immediate connection between crystallography theory and their own lab experiences, leading to a deeper understanding of crystallography content and making their brief laboratory visit a memorable experience.

We summarized our approach in doi.org/10.1021/acs.... @pubs.acs.org 😀 Any supportive crystallographic facility can offer this experience to #undergrad or #K12 students annually. Faculty can also reach out to arrange similar visits. #crystallography #education

<italic toggle&#x3D;"yes">In Crystallo</italic> Photochemistry: Reimagining Synthetic Tractability with Transparent Single-Crystalline Flasks Expanding the boundaries of synthetic tractability ─ of what molecules can be synthesized and isolated ─ is an eternal challenge for synthetic chemists. The development of new synthetic methods and strategies enables the properties and potential functions of novel molecular targets to be experimentally evaluated. In the context of catalysis, predictable synthetic strategies are often available to access kinetically persistent intermediates such as catalyst resting states. In contrast, synthesis and characterization of the reactive intermediates are often not possible due to the fleeting lifetimes of these species. In crystallo photochemistry combines single-crystal matrix isolation with cryogenic photochemistry to enable reactive intermediates to be synthesized under conditions in which they are persistent and can be (crystallographically) characterized. This Outlook highlights key achievements of in crystallo photochemistry as well as discusses opportunities and challenges that confront realization of the potential of in crystallo synthesis to redefine the boundaries of synthetic tractability.

Did you check the NMR or MS by re-disolving the crystals?🤔

Based on the solution, there should be three target molecules, but they simply deleted other two😂😂

This was also my student's first reaction, so he downloaded the CIF and figured out what had gone wrong. 😀Yes, the original R1 is 0.98. 😂

While prepping for group meeting, a student spotted a structure with R1 = 0.9813 (!) in pubs.acs.org/doi/10.1021/... @ccdc.cam.ac.uk 😱 and used what he learned in #Chem255 to refine it to R1 < 0.06—after squeezing out mystery solvents. What an achievement! 🥳 #crystallography #education
