Abstract
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.
