摘　　要：测定了三元体系Er(NO_3)_3。—Met—H_2O在25℃时的溶度和饱和溶液的折光率,结果表明该体系可形成两种配合物,即Er(Met)(NO_3)_3·H_2O与E_r(Met).(NO_3)_3·6H_2O。用相平衡方法合成了 1:4型配合物,通过元素分析、IR、UV、X 粉末衍射、TG—DTG与DSC对其进行了物化性质表征,并讨论了配合行为。:The system of Er(NO3)3 -Met-H2O has been studied. Solubilities and refraction in-dices of saturated solutions of this system have been measured at 25±O. 05℃ and corresponding eguilibrium diagrams have been constructed. In this system there are two coordination complexes: Er(Met)(NO3)3H2O and Er(Met)4(NO3)3·6H2O. The solid complex of Er(Met)4(NO3)3 6H2O has been characterized by chemical analysis,IR sepctra,electronic spectra ,X-ray diffrac-tion,TG-DTG and DSC.
