• The role of structural change in the first-order magnetic-nonmagnetic phase transition in the triangular lattice compound LiVO_2 has been studied by means of X-ray four-circle and differential scanning calorimetric analyses. A set of reflections of the (1/3 1/3 0) vector have been observed accompanied by diffuse streaks along the c*-axis in nearly stoichiometric crystals at room temperature. The analyses of average structure suggest a displacement of V ions of about 0.1 Å from the ideal sites within the basal plane. On the basis of the difference between the change in internal energies and that in magnetic energies above and below the transition temperature T_<c1, 2>, the lattice below T_<c1, 2> has been found to be more unstable than that above T_<c1, 2>.
