Cover illustration: Perhaps as a result of its highly deliquescent nature, the X-ray crystal structure of trichloroacetic acid has not been reported until now. This low-temperature study reveals that the molecules form centrosymmetric pairs, leading to hydrogen-bonded dimers. See Rajagopal, Mostad, Krishnakumar, Subha Nandhini & Natarajan [Acta Cryst. E59, o316-o318].
