Results of Ni EXAFS analysis of the Ni(II) first shell structure under ambient conditions.

The results for 3.12 and 5.06 mol∙kg^-1 NiCl₂ solutions using X-ray diffraction [21,25] are also listed. The concentrations are expressed in molality (mol∙kg^-1). Uncertainty limits are given in parentheses.

^a Value fixed (not optimized) during refinements.

^b Sum of number of O and Cl fixed to be equal to 6.

^c Solid standard.

^d Concentration in molarity (mol∙L^-1) in references [21,25], converted to molality (mol∙kg^-1).
