            While working on these structures, I encountered disorder, non-merohedric and pseudo-merohedric twins, cases where the unit cellβs metric symmetry exceeds that of the crystal, and other crystallographic complications. It has been a fascinating and rewarding experience! #research

            Most of these structures were collected at room temperature on a Gemini S diffractometer (@rigakuoxfordxrd.bsky.social) assembled in 2007. The dataset comprises mainly coordination compounds with organic ligands, as well as various organic molecules, including natural product derivatives.

            "In 2019, at the ECM in Vienna [...] a crystallographer in the audience improvised a concise speech thanking George for the contribution in his programs, which was unanimously backed by a standing ovation."
I was present there and vividly remember this moment.
