Abstract

[H₄Ni₁₀(H₂O)₈Nb₃₂O₁₀₂]²⁰⁻, representing the first high-nuclear nickel-cation-bridged polyoxoniobate, has been synthesized. It incorporates two [{Ni₂O₄}(H₂O)₂(Nb₆O₁₉)]¹²⁻ and two [Ni₃(H₂O)₂Nb₁₀O₃₄]¹²⁻ subunits exhibiting a rhombus-like architecture. Furthermore, the solution behaviour was examined by electrospray ionization mass spectrometry and the magnetic properties in the low temperature range indicate the presence of ferromagnetic interactions.
