摘要：

Structure data for both triclinic alpha- and gamma-CuMoO4 have been delivered with anisotropic temperature factors at 190 K. The complete tensors of linear thermal expansion coefficients were derived for alpha- and gamma-CuMoO4 using the temperature dependence of lattice parameters within the temperature range 20 K-300 K and 20 K-260 K, respectively. The orientation of principal axes and values of principal expansion coefficients are given for selected temperatures. Their relation to the structure is discussed. The volume expansion coefficient of a CuMoO4 becomes negative below 80 K.
