| Abstract: | The complex Gd2(Gly)6(H2O)4](ClO4)6(H2O)5 was synthesized by a microwave technology characterized by IR spectra and a TG-DTG technique. The crystal structure of the complex was determined by an X-ray diffraction method. The crystal is a 1D chain structure, which belongs to a triclinic system with space group P , and cell parameters: a＝1.1569(17) nm, b＝1.4138(2) nm, c＝1.5642(2) nm, α＝96.910(2)°, β＝102.735(2)°, γ＝105.512(2)°, V＝2.3606(6) nm3, Z＝2, and Dc＝2.144 g•cm－3. By isoperibol solution-reaction calorimetry, the standard molar enthalpy of formation of the complex was determined to be －(7960.73±3.23) kJ•mol－1. |
