摘要：

The ionic coordination of Mg(NO3)2 in aqueous solutions has been investigated by X-ray diffraction. The experimental correlation functions appear to be characterized by the hydration of the cation. Satisfactory agreement with the experimental data has been reached through a model in which: (i) the nitrate ions do not produce any structuring effect in their neighbourhood; (ii) the Mg2+ ions possess an inner hydration shell of six water molecules and a second coordination shell. © 1979.
