摘要
利用微波技术合成了配合物[Gd2(Gly)6(H2O)4](ClO4)6(H2O)5,进行了化学成分分析、红外表征和热重分析.应用X衍射仪测定其晶体结构,该晶体为一维链结构,属三斜晶系,P?1空间群,晶胞参数: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,Dc=2.144g?cm-3.采用精密溶解-反应量热计,通过设计热化学循环,计算出了该配合物的标准摩尔生成焓为-(7960.73±3.23)kJ?mol-1.
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 P1^-, 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)nm^3,Z=2,and Dc=2.144g·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.
