Abstract

The infrared and Raman spectra of Na[FeEDTA(H(2)O)]x2H(2)O and Na(4)[(FeEDTA)(2)O]x3H(2)O (EDTA=tetra anion of ethylenediaminetetraacetic acid), two complexes proposed as adequate for iron supplementation, were recorded and analyzed in relation to its structural peculiarities. Some comparisons between the recorded spectra are also presented, and the characteristics of the carboxylate motions as well as those of the metal-to-ligand vibrations are discussed in detail.

摘要

Na[FeEDTA(H(2)O)]x2H(2)O 和 Na(4)[(FeEDTA)(2)O]x3H(2)O（EDTA=乙二胺四乙酸的四阴离子）的红外和拉曼光谱，这两种被提议作为铁补充剂的复合物，被记录下来并进行了分析，以研究其结构特性。还对记录的光谱进行了一些比较，并详细讨论了羧酸根运动的特征以及金属-配体振动的特征。
