| 英文摘要 | the crystal structure and composition of (c12h25nh3)(2)zncl4(s) were characterized by chemical and elemental analysis. x-ray powder diffraction technique and x-ray crystallography. the lattice energy of the title compound was calculated to be u-pot=888.82 kj.mol(-1). low temperature heat capacities of the title compound have been measured by a precision automated adiabatic calorimeter over the temperature range from 80 to 403 k. an obvious solid to solid phase transition occurred in the heat capacity curve, and the peak temperature, molar enthalpy and molar entropy of the phase transition of the compound were determined to be t-trs=(364.02 +/- 0.03) k, delta h-trs(m) = (77.567 +/- 0.341) kj.mol(-1), and delta s-trs(m)=(213.77 +/- 1.17) j.k-1.mol(-1), respectively. experimental molar heat capacities before and after the phase transition were respectively fitted to two polynomial equations. the smoothed 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. |
