A data-driven approach to predicting co-crystal formation reduces the number of experiments required to successfully produce new co-crystals. A machine learning algorithm trained on an in-house set of co-crystallization experiments results in a 2.6-fold enrichment of successful co-crystal formation in a ranked list of … Read the rest

We present here the crystallisation outcomes for 319 publicly available compounds in up to 18 different solvents spread over 5710 individual single solvent evaporation trials. The recorded data is part of a much larger, corresponding in-house database and includes both positive as well as negative crystallisation … Read the rest
Congratulations to Part II students Laura Fenwick and James Walker who both won poster prizes awarded by the Chemical Crystallography Group of the British Crystallographic Association at the Annual Spring Meeting in Lancaster.

A new molecular descriptor, nConf20, based on chemical connectivity, is presented which captures the accessible conformational space of a molecule. Currently the best available 2-dimensional descriptors for quantifying the flexibility of a particular molecule are the rotatable bond count (RBC) and the Kier flexibility index. 
The sixth Moroccan school of Crystallography was held in November 2016 at Université Moulay Ismaïl in the historic Moroccan city of Meknes. Richard Cooper gave a lecture on Structure Validation and Visualisation and a one day workshop on Refinement and Validation using the CRYSTALS software.… Read the rest

Hydrogen bonding with fluoride is a key interaction encountered when analyzing the mode of action of 5′-fluoro-5′-deoxyadenosine synthase, the only known enzyme capable of catalyzing the formation of a C-F bond from F–. Further understanding of the effect … Read the rest

Direct determination of the Flack parameter as part of the structure refinement procedure usually gives different, though similar, values to post-refinement methods. The source of this discrepancy has been probed by analysing a range of data sets taken from the recent literature. Most significantly, … Read the rest
