| 英文摘要 | the heat capacities of two kinds of rare-earth element solid complexes with isoleucine [re-2(ile)(4)(h2o)(8)](clo4)(6) (where re = nd, er, and ile = isoleucine) have been measured by an automatic adiabatic calorimeter in the temperature range from 80 to 370 k. two solid-solid phase transitions were found from the c-p curve of nd formed complex in the range of 165-175 k with a peak temperature of 167.88 k and in the range of 195-210 k with a peak temperature of 202.13 k. the corresponding molar enthalpies of these phase transitions were determined to be 404.61 j mol(-1) and 2.955 kj mol(-1), respectively. one solid-solid phase transition was found for the er formed complex in the range of 190-205 k with a peak temperature of 193.42 k. the corresponding molar enthalpy of this transition was 14.11 kj mol(-1). smooth heat capacities and thermodynamic functions relative to the standard state (298.15 k), h-t - h-298.15, s-t - s-298.15 and -[g(t) - g(298.15)], of the two compounds, were calculated on basis of experimental heat capacity data. possible mechanisms of thermal decompositions for the pair of compounds were suggested according to the thermogravimetric (tg) analysis.
