The cool images on this week’s cover are from Giuseppe Resnati, NFMLab, and James C. Anderson, UCL.

Resnati and colleagues have conducted an NMR study of phosphate oxoanion binding of a 2-iodo-imidazolium receptor with charge assisted halogen bonding, finding a surprisingly strong binding constant for phosphate anions, their work is highlighted on the outside front cover.

On a completely different topic, Anderson and Moreno have been using CO₂ to produce ureas at ambient conditions, using 12- and 14- electron titanium imido complexes:
