Аннотация: Copper samarium germanate CuSm2Ge2O8 have been synthesized by the ceramic method from CuO, Sm2O3, and GeO2 in air at the final calcination temperature 1273 K (200 h), and its crystal structure has been determined (space group Cm; a = 9.7592(2) angstrom, b = 15.2608(4) angstrom, c = 8.2502(2) angstrom, beta = 148.2566(8)degrees, V =Показать полностью646.46(3) angstrom(3)). The temperature dependence of the molar heat capacity C-p= f(T) measured in the temperature range 350-1000 K shows a maximum at T-max = 498.5 K caused by the phase transition. Thermodynamic properties have been calculated from experimental data.
