ResumoAbstract The infrared spectra between 600 and 4000 cm −1 of Co 3 (OH) 2 (SO 4 ) 2 · 2H 2 O, Co 3 (OH) 2 (SO 4 ) 2 , and Co 3 (OD) 2 (SO 4 ) 2 · 2D 2 O are reported and discussed. The spectra are mainly examined in relation to the binding state of the water molecules. The results are in good agreement with the previously described crystal structure studies. Thermogravimetry, differential thermal analysis and X ‐ray diffraction methods were used to investigate the unusual thermal decomposition behaviour of Co 3 (OH) 2 (SO 4 ) 2 · 2H 2 O. The kinetics of the dehydration reaction are discussed.
