- Both $(NbSe_4)_3I$ and (NbSe_4)_{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 $NbSe_4$ 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 $(NbSe_4)_{10//3}I$ compound undergoes structural phase transition to monoclinic phase, $(NbSe_4)_3 I$ remains in tetragonal symmetry. Iodine atoms are responsible for the differences in $(NbSe_4)_{10//3}I$ and $(NbSe_4)_3 I$ structures causing different spacing in the infinite $NbSe_4$ chains.
