摘要: 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 the presence Et4NBr leads to formation colorless crystals (Et4N)4[Nb2O2(C2O4)4(μ-C2O4)] (1). characterization obtained compound by single crystal and powder XRD, IR Raman spectroscopy, elemental analysis allows clarify processes occurring with aqueous solutions.
