文摘

The charge-neutral antimonatopolyoxovanadium(IV) cluster [V^IV₁₆Sb^III₄O₄₂(H₂O){V^IVO(C₆H₁₄N₂)₂}₄]·10H₂O·C₆H₁₄N₂ was obtained under solvothermal conditions. The central cluster fragment, [V^IV₁₆Sb^III₄O₄₂], is a derivative of the [V₁₈O₄₂] archetype and is formed by replacing two VO₅ polyhedra by two Sb₂O₅ units. The {V₂₀Sb₄} structure expands the {V₁₆Sb₄} motif by the addition of four square-pyramidal, terminal VO(1,2-diaminocyclohexane)₂ groups. At low temperatures, the magnetic ground state is characterized by four independent S = ¹/₂ sites.
