Composition of Ni~(2+) cation solvation shell in NiCl2-methanol solution by multinuclear NMR

摘要

~1H-, ~2H- and ~(13)C-NMR spectra have been used to test the Ni~(2+) solvation shell composition in the 1.1 molal methanol solution of NiCl_2. It has been confirmed that Cl- anion takes part in the nearest environment of Ni~(2+) cation at all the temperatures investigated. Using 2H-NMR allowed us to detect for the first time OD-signal of methanol in the primary solvation shell of Ni~(2+) cation. Both ~2H- and ~(13)C-NMR spectra show that the composition of the cation solvation shell becomes more complicated at temperatures lower than 220 K.
