Coordination biopolymers, namely, nickel complexes of sodium pectate, have been actively studied in recent years as promising representatives of non-platinum catalysts for proton exchange membrane fuel cells. The structure of coordination polymers consisting of natural precursors is complex and not entirely regular. It presents significant difficulties in determining the internal structure of coordination polymers. Identifiable electron paramagnetic resonance (EPR) signals of various Mn2+ units in sodium pectate manganese complexes have provided important structural information in systems similar in composition to nickel coordination biopolymers. In addition, the manganese complexes with the natural pectin polymers themselves are of interest as non-platinum PEMFC catalysts
