摘要：

H-1-, H-2-and C-13-NMR spectra have been used to test the Ni2+ solvation shell composition in the 1.1 molal methanol solution of NiCl2. It has been confirmed that Cl- anion takes part in the nearest environment of Ni2+ cation at all the temperatures investigated. Using H-2-NMR allowed us to detect for the first time OD-signal of methanol in the primary solvation shell of Ni2+ cation. Both H-2- and C-13-NMR spectra show that the composition of the cation solvation shell becomes more complicated at temperatures lower than 220 K.
