Both (NbSe₄)₃I and (NbSe₄)_{10/3}I compounds are interesting system possessing quasi one-dimensional linear chain character and exhibiting nonlinear transport properties with a second order phase transition. The compounds are built of NbSe₄ antiprisms, stacked along the tetragonal c axis into chains in a screw-like arrangement. Performed X-ray low temperature single crystal diffraction measurements allowed to solve, refine and analyze crystal structures of both compounds at 14 K. While (NbSe₄)_{10/3}I compound undergoes structural phase transition to monoclinic phase, (NbSe₄)₃I remains in tetragonal symmetry. Iodine atoms are responsible for the differences in (NbSe₄)_{10/3}I and (NbSe₄)₃I structures causing different spacing in the infinite NbSe₄ chains.
