摘要
该文合成了茶氨酸与金属M(Ⅱ)离子配合物。通过红外、化学分析确定配合物的化学组成为M[((C_7H_(12)N_2O_3)_2](M=Zn^(2+),Cu^(2+),Mn^(2+))。在HR-15型静态氧弹热量计上测定了配合物的燃烧热,根据热化学原理计算出配合物的标准生成焓,结果ΔfH_m~ΘZn[(C_7H_(12)N_2O_3)_2]=-3175.53kJ/mol,ΔfH_m~ΘCu[(C_7H_(12)N_2O_3)_2]=-2490.13kJ/mol,ΔfH_m~ΘMn[(C_7H_(12)N_2O_3)_2]=-2955.33kJ/mol。
In this paper, several complexes of transition metallic element with theanine have been synthesized, and the chemical formula of complexes was determined by chemical analysis and IR, they are M[ （C7 H12 N2 O2 ）2], （M= Zn2＋ ,Cu2＋ , Mn2＋ ）. The heat of combustion of the complexes had been determined by using HR-15 static oxygenbomb calorimeter. The standard enthalpies of formation were calculated for these complexes. The recommended values of standard enthalpy of formation is △f θ Hm Zn [（C7H12 N2O3 ）2] =- 3 175. 53 kJ/mol, △fHm θCu[（C7H12 N2O3 ）2] =- 2 490. 13 kJ/mol, △fHmθMn[（C7H12 N2O3 ）2 =-2 955.33 kJ/mol.
