Struktur und Schwingungsspektrum des Kaliumundecawolframats Kg6H4W11O38· 11H2O / Structure and Vibrational Spectrum of the Potassium Undecatungstate K6H4WnO38 -11 H2O

Abstract The title compound crystallizes in the triclinic space group P1̅ with lattice parameters a = 13.129 Å, b = 14.156 Å, c = 14.843 Å and α= 88.34°, β = 74.43°, γ = 70.86°. The polyanion evidently is the predominant species in pseudometatungstate phases the exact composition of which has not previously been determined.
