Differential scanning calorimetry (DSC) and X-ray diffraction
measurements have been performed on diammonium cobalt disulphate
hexahydrate and deuterated
crystals. Several transitions in both
compounds at high temperature have been found by the DSC measurements.
The structures of both compounds are redetermined accurately at room
temperature. The isotope effect in these crystals has been studied. It
is confirmed that the changes of O-H-O hydrogen bond length by the
substitution of deuterium for hydrogen are in good agreement with that
of many crystals with hydrogen bonds as previously reported by
Ichikawa.
