英文摘要a novel compound-monohydrated nickel nicotinate was synthesized by the method of room temperature solid phase synthesis and ball grinder. ftir, chemical and elemental analysis, tg/dtg, and x-ray powder diffraction technique were applied to characterize the structure and composition of the coordination compound. low-temperature heat capacities of the solid coordination compound have been measured by a precision automated adiabatic calorimeter over the temperature range from 78 to 386 k. a solid-solid phase transition occurred in the temperature range of 328-358 k in the heat capacity curve, and the peak temperature, the molar enthalpy and molar entropy of the phase transition were determined to be t-trs = (356.759 +/- 0.697) k, delta h-trs(m) = (13.650 0.408) kj.mol(-1), and delta s-trs(m) = (38.279 +/- 0.086) j.k-1.mol(-1), respectively. the experimental values of the molar heat capacities in the temperature ranges of 78-328 k and 358-386 k were fitted to two polynomials, respectively. the polynomial fitted values of the molar heat capacities and fundamental thermodynamic functions of the sample relative to the standard reference temperature 298.15 k were calculated and tabulated at the intervals of 5 k.
