I previously used data mining of crystal structures to explore the directing influence of substituents on aromatic and heteroaromatic rings. Here I explore, quite literally, a different angle to the hydrogen bonding interactions between a benzene ring and OH or NH groups.

How does an OH or NH group approach an aromatic ring to hydrogen bond with its π-face?
Wednesday, June 22nd, 2016A wider look at chlorine trifluoride: crystal structures and data mining.
Friday, June 10th, 2016A while ago, I explored how the 3-coordinate halogen compound ClF3 is conventionally analyzed using VSEPR (valence shell electron pair repulsion theory). Here I (belatedly) look at other such tri-coordinate halogen compounds using known structures gleaned from the crystal structure database (CSD).
A two-publisher model for the scientific article: narrative+shared data.
Sunday, September 15th, 2013I do go on rather a lot about enabling or hyper-activating[1] data. So do others[2]. Why is sharing data important?

Research data and the “h-index”.
Monday, June 24th, 2013The blog post by Rich Apodaca entitled “The Horrifying Future of Scientific Communication” is very thought provoking and well worth reading. He takes us through disruptive innovation, and how it might impact upon how scientists communicate their knowledge. One solution floated for us to ponder is that “supporting Information, combined with data mining tools, could eliminate most of the need for manuscripts in the first place“. I am going to juxtapose that suggestion on something else I recently discovered.
