Tris(1,2-dimethyl-3-hydroxy-4(1H)-pyridone)oxotantalum(v): a new water-soluble tantalum complex containing the [Ta
O]3+ core
Abstract
The synthesis, the characterization and the X-ray crystal structure of a novel tantalum(V) complex tris(1,2-dimethyl-3-hydroxy-4(1H)-pyridone)oxotantalum(V) [TaO(C7H8O2N)3] 1 is reported. Starting from the tantalum pentaethoxide a two-step reaction was carried out observing rigorous anhydrous conditions in O]3+ core in the triclinic space group P
, a = 7.282(3), b = 14.055(5), c = 16.987(6) Å, α = 65.704(5), β = 89.155(6), γ = 75.270(6)°, V = 1525(1)Å3, Z = 2. Spectroscopic investigation reveals that the complex is highly soluble and stable in
