Аннотация

The bis(oxalate) complex of niobium (NH₄)[NbO(C₂O₄)₂(H₂O)₂]·3H₂O can be dissolved in DMF on heating. Ether diffusion into this solution in the presence of Et₄NBr leads to the formation of colorless crystals of (Et₄N)₄[Nb₂O₂(C₂O₄)₄(μ-C₂O₄)] (1). The characterization of the obtained compound by single crystal and powder XRD, IR and Raman spectroscopy, and elemental analysis allows to clarify processes occurring with the bis(oxalate) niobium complex in aqueous solutions.
