• The anomalous states produced by electron capture decay of <SUP>57</SUP>Co in CoCl<SUB>2</SUB>·2H<SUB>2</SUB>O and CoCl<SUB>2</SUB>·6H<SUB>2</SUB>O are investigated using conventional Mössbauer emission spectroscopy and a γ-X ray coincidence method which allows to isolate events with a reduced influence of the Auger electron self-irradiation. The formation of the anomalous electronic and structural configuration is assigned to the self-radiolysis of the water ligands. The mechanism involves both the nearest and the next nearest H<SUB>2</SUB>O coordination shell according to the densities of these ligand molecules in the respective shells.
