An analysis of plausible crystal structures of R-phase and precursory structures in Ti-Ni based on solely kinematical data on presence and equivalence of extra-reflections of diffraction patterns, as well as further data on symmetry of structure was carried out. A character of possible ordering and displacements, required to form these phases from parent BCC lattice, was determined. A classification of possible structures was given.
