METHOD OF SYNTHESIS OF CRYSTALLINE NITRATE METALLATE (METAL = V, Mn, Fe, Cu, Zn, Dy, Er, Yb) COMPLEXES WITH N-NITROPYRIDINIUM CATION Russian patent published in 2024 - IPC C01B21/48 C07D213/26 

FIELD: nitrate complexes.

SUBSTANCE: invention relates to a technology for creating and processing crystalline nitrate metal complexes with the N-nitropyridinium cation. The following is proposed: a method of the synthesis of nitrate metallate complexes with the N-nitropyridinium cation by reacting pyridinium nitrate and d- or f-metal nitrate in a molar ratio of 1:1 or 1:2 with nitric anhydride in a evacuated desiccator over phosphoric anhydride with the formation of crystalline complexes, which include N-nitropyridinium cation.

EFFECT: production of nitrate complexes of d- or f-metals with the N-nitropyridinium cation with a yield of at least 60% and a purity of at least 95 wt.%.
