N2 - CuMo3O10 · H2O crystals have been obtained by hydrothermal synthesis as a result of reaction between (NH4)6Mo7O24 · 4H2O and Cu(CH3COO)2 at 220 °C during 7 days. The X-ray powder diffraction data in wide range of temperature have shown that the studied phase is stable within the range from –180 to 300 °С. Its thermal expansion is anisotropic, thermal expansion coefficients, calculated at Т = 100 °С, are: αa = 28.5, αb = 6.1 and αc = 13.3 °С–1. Structural changes have been analyzed by the structure refinement method based on the single-crystal X-ray diffraction data at different temperatures. Thermal expansion anisotropy is connected with the chain-structure type and the angle deformations caused by changes in inter-atomic angles in the CuO6 octahedra and in inter-polyhedral angles between copper octahedron and trimolybdate chains. The high-temperature behavior of CuMo3O10 · H2O is compared in the paper with behavior of chemically close copper molybdates – lindgrenite, szenicsite and cupromolybdate.
