complexes of lighter lanthanide nitrates with N,N′-dinaphthyl-N,N′-diphenyl-3,6-dioxaoctanediamide (DDD), Ln(NO3)3(DDD) (Ln LaNd, Sm) have been prepared in non-aqueous media. These complexes have been characterized by elemental analysis, conductivity measurements, IR spectra, electronic spectra and TG-DTA techniques. In all the complexes, DDD and NO3− are coordinated to the lanthanide ions as tetradentate
摘要已经研究了较轻的硝酸镧系元素与N,N'-二萘基-N,N'-联苯-3,6-二氧八辛二酰胺(DDD),Ln(NO3)3(DDD)(LnLaNd,Sm)的固体配合物在非水介质中配制。这些配合物已通过元素分析,电导率测量,IR光谱,电子光谱和TG-DTA技术进行了表征。在所有络合物中,DDD和NO3-与镧系离子配位分别为四齿和二齿配体。讨论了这些配合物与硝酸镧系元素与N,N,N',N'-四苯基-3,6-二氧杂辛烷二酰胺(TDD)的红外光谱和电子光谱的差异。
