FIELD: inorganic synthesis.
SUBSTANCE: invention provides heterometallic neodymium (III) and iron (III) malate having formula I: 
appropriate for synthesis of mixed oxides with perovskite structure, which are used as catalysts in oxidative catalysis of unsaturated acyclic hydrocarbons and as materials used in microwave frequency technology and in computer memory materials. Preparation consists in electrolysis of concentrated aqueous solution of neodymium (III) chloride and malic acid at 1:3 ratio in presence of pyridine with pressed reduced iron anode and inert cathode at anode current density 1 A/cm2, followed by separating precipitate and washing it with organic solvent before drying.
EFFECT: enlarged assortment of oxidation catalysts.
