X-Ray crystal structure of caesium hydrogen bis(monofluorosulphate), Cs+[O2FSO.H.OSFO2]–, with a very short hydrogen bond
Abstract
X-ray diffraction provides the first evidence for the existence of the homoconjugated anion [O2FSO.H.OSFO2]– containing a very short and symmetrical hydrogen bond [O⋯O = 2.41(1)Å].
