Assessing covalency in the hydrogen bond zoo

Jennifer Newton writes about a hot ChemComm article for Chemistry World

Covalency, a term describing bonding by sharing electrons, divides opinion when mentioned alongside hydrogen bonding. Worried that the concept of hydrogen bonding has been getting fuzzier over time, scientists in Germany have sought a fresh look at the very nature of these bonds, and how much covalency they involve.

Richard Dronskowski and colleagues at RWTH Aachen University collected evidence from hydrogen-bonded molecular crystals to elucidate how these crystals are held together and compare the covalency of long and short hydrogen bonds.
