英文摘要 | a new crystalline complex (c8h17nh3)(2)cucl4(s) (abbreviated as c8cu(s)) was synthesized by liquid phase reaction. chemical analysis, elemental analysis, and x-ray crystallography were applied to characterize the composition and crystal structure of the complex. low-temperature heat capacities of the complex were measured by a precision automatic adiabatic calorimeter over the temperatures ranging from 78 to 395 k, and two solid-solid phase changes appeared in the heat capacity curve. the temperatures, molar enthalpies and entropies of the two phase transitions of the complex were determined to be: t (trs, 1) = 309.4 +/- a 0.35 k, delta(trs) h (m, 1) = 16.55 +/- a 0.41 kj mol(-1), and delta(trs) s (m, 1) = 53.49 +/- a 1.3 j k-1 mol(-1) for the first peak; t (trs, 2) = 338.5 +/- a 0.63 k, delta(trs) h (m, 2) = 6.500 +/- a 0.10 kj mol(-1), and delta(trs) s (m, 2) = 19.20 +/- a 0.28 j k-1 mol(-1) for the second peak. two polynomial equations of the heat capacities as a function of the temperature were fitted by least-square method. smoothed heat capacities and thermodynamic functions of the complex relative to the standard reference temperature of 298.15 k were calculated based on the fitted polynomial equations. |
