FIELD: chemistry.
SUBSTANCE: invention relates to the preparation of organometallic lanthanum frame compound of the formula La2(VDS)3(H2O)4 of a three-dimensional structure based on terephthalic acid, which can be used as a catalyst for various processes, including photocatalyst. The method for lanthanum organometallic frame compound preparation comprises terephthalic acid reaction with lanthanum nitrate for 8-9 hours at a temperature of 150-155°C in a solvent represented by dimethylformamide, reaction mixture coolong down to the room temperature, filtration of the resulting solid, successive washing of the solid phase by dimethylformamide and ethanol and drying at a temperature of 140-160°C.
EFFECT: simplified synthesis conditions, increased process efficiency and increased yield.
