Abstract
The aqueous solution chemistry of niobium is underex-plored, and well characterized aqua complexes are scarce. In this con-tribution, a new niobium aqua complex was obtained by treatment of Zn-reduced ethanolic solution of NbCl5 with HCl in the presence of aselenide source (ZnSe). This is the first example of selenium containing aqua complex of niobium.
The yellow-green aqua complex was isolated by cation-exchange chromatography and transformed into corresponding isothiocyanate complex by ligand exchange, which was crystallized as (PyH)4.5[H1.5Nb4SeO5(NCS)10]·0.5H2O. X-ray structural analysis revealed a metal-metal bonded tetranuclear{Nb4(μ4-Se)(μ2-O)5}4+ core with a capping μ4-Se ligand.
