英文摘要 | a novel compound-monohydrated cupric nicotinate was synthesized by the method of room temperature solid phase reaction and a ball grinder. ftir, chemical and elemental analyses and x-ray powder diffraction techniques were applied to characterize the structure and composition of the complex. 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 400 k. a melting process occurred in the temperature range of 326-346 k in the heat capacity curve, and the melting point, molar enthalpy and entropy of the fusion were determined to be t(fus)= (341.290 +/- 0.873) k, delta(fus)h(m)=(13.582 +/- 0.012) kj.mol(-1), delta(fus)s(m)=(39.797 +/- 0.067) j.k(-1).mol(-1). the experimental values of the molar heat capacities in the temperature regions of 78-326 k and 346-400 k were respectively fitted to two polynomial equations. the polynomially 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 an interval of 5 k. |
