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).
