英文摘要: A complex of holmium perchlorate coordinated with L-glutamic acid, [Ho-2(L-Glu)(2)(H2O)(8)](ClO4)(4)center dot H2O, was prepared with a purity of 98.96%. The compound was characterized by chemical, elemental and thermal analysis. Heat capacities of the compound were determined by automated adiabatic calorimetry from 78 to 370 K. The dehydration temperature is 350 K. The dehydration enthalpy and entropy are 16.34 U mol(-1) and 16.67 J K-1 mol(-1), respectively. The standard enthalpy of formation is -6474.6 kJ mol(-1) from reaction calorimetry at 298.15 K. (C) 2005 Elsevier B.V. All rights reserved.
