Abstract
Data for iron and manganese-containing sodium pectate complexes are reported. Such complexes are potentially capable of exhibiting catalytic properties to the electroreduction of small molecules. Also, the complexes are water-soluble due to their ligands. The combination of these factors makes them promising for homogeneous electrocatalysis. However, in many respects, these complexes remain poorly understood. The Fourier-transform infrared spectroscopy data for the sodium pectate complexes with manganese and iron in the range of 500-4000 cm(-1) were obtained. The electron spin resonance spectra of the complexes make it possible to characterize oxidation states of the metal centers in the complexes. The cyclic voltammetry data for the complexes both in an aqueous solution saturated with argon and saturated with carbon dioxide were received. For both complexes after deposition of the complexes on graphite managed to get micrographs by the atomic force microscopy method.
