Using method of the high-temperature radiography in situ the authors researched the thermal expansion of the monoclinic structure β-Mn2V2O7 within the temperature range of 100-700 °C. They prove that the expansion is aeolotropic and caused by deformation shearing. The balance metal-oxygen polyhedron increases when heating, the interpolyhedral spaces decreases, the zig-zag form of the manganese-oxygen systems is less significant.
