We show that the magnetic properties of antiferromagnetic layered NiCl$_{2}$ can be altered under nano-sizing depending on dimensionality and morphology type of the corresponding nano-forms. By means of Monte-Carlo simulations within classical Heisenberg model, the spin ordering, magnetic part of heat capacity C$_{v}$ and N\'eel temperatures T$_{N}$ for multi-walled NiCl$_{2}$ nanotubes and a fullerene were calculated and analyzed in comparison with the bulk NiCl$_{2}$ and multilayered two-dimensional NiCl$_{2}$ crystals and nanostripes. We have found that the nano-structuring of NiCl$_{2}$ at the size reducing and at the formation of the closed structures can influence propitiously on the preservation of antiferromagnetic properties.
