Structural investigations at high temperature were carried out on compound Li 2 VOSiO 4 , which crystallises with a natisite-type structure. Unit-cell parameters were measured and diffracted intensities collected at regular intervals in the temperature range 25–500 °C using single crystal X-ray diffraction techniques. Thermal expansion coefficients showed positive expansion of lattice constants, greater along the  c  direction, and of cell volume. Reversibility of thermal expansion in the investigated temperature range was checked by measuring unit-cell parameters after the crystal was cooled down from 500 °C to room temperature. Structure refinements revealed that the [VOSi 4 ] n  2−  layers are almost rigid and that the most relevant modifications occur at the intercalated ion layer.
