| 英文摘要 | low-temperature heat capacities of the coordination compound zn(phe)(3)(no3)(2) . h2o(s) have been precisely measured over the temperature range between t = 78 k and t = 373 k through a small sample precision automated adiabatic calorimeter. experimental heat capacities have been fitted into a polynomial equation of heat capacities (c-p,c-m) with the reduced temperatures (x), [x = f(t)]. the initial dehydration temperature of the complex (t-d) has been given from analysis of the heat-capacity curve, t-d = 327.25 k. dissolution enthalpies of [znso4 . 7h(2)o(s) + 2nano(3)(s) + 3l-phe(s)] (delta(d)h(m,l)(0)) and [zn(phe)(3)(no3)(2) . h2o(s) + na2so4(s)] (delta(d)h(m,2)(0)) in 100 ml of 2 molar hcl at t = 298.15 k have been measured by means of an isoperibol solution calorimeter: delta(d)h(m,l)(0) = (115.430 +/- 2.797)kj . mol(-1), delta(d)h(m,2)(0) = (67.211 +/- 2.147)kj . mol(-1). the standard molar enthalpy of formation of the complex has been determined to be: delta(f)h(m)(0) = -(2292.44 +/- 11.12)kj . mol(-1), through a hess thermochemical cycle from the results of molar dissolution enthalpies and other auxiliary thermodynamic data.
