Lithium vanadate Li(3+x)V6O13 at low temperature.
The structure of Li(3+x)V6O13 [x = 0.24 (3)] at 95 K has been solved and refined using single-crystal X-ray diffraction. The refined lithium content corresponds to two fully occupied Li sites and one partially occupied Li site. A doubling of the c axis is observed upon cooling from room temperature, and this change is associated with shifts of the V atoms. The resulting space group is C2/c. The Li disorder present in the Li3V6O13 phase at room temperature is also observed in the low-temperature phase reported here.
