FIELD: chemistry.
SUBSTANCE: invention refers to coordination chemistry: specifically, to improved method of producing heterometal neodymium (III) and iron (III) malate of formula 1 to be used for synthesis of mixed oxides of perovskite composition. 
. Method is enabled by electrolysis of concentrated aqueous solution of neodymium (III) nitrate and malic acid in ratio 1:3 with pyridine or lithium perchlorate with anode added, pressed from recovered iron, and inert cathode from graphite with using pulse current of variable porosity. Thereafter the solution is evaporated with precipitation then washed with ethanol and dried.
EFFECT: method is cost-effective, controlled and productive.
