Abstract

The hydrothermal reaction of RbVO₃, (NH₄)₂B₄O₇ · 4H₂O, ethylenediamine (en), and H₂O in a mole ratio of 1:8:2:135 heated at 170°C for 5 days produces pale green crystals of the novel polyoxovanadium borate cluster compound Rb₄[(VO)₆{B₁₀O₁₆(OH) ₆}₂] · 0.5H₂O (1) which contains [V₆B₂₀O₃₈(OH)₁₂]⁴- clusters, each cluster comprising a nearly hexagonal ring of six trans-edge-sharing VO₅ square pyramids capped on each side by a B₁₀O₁₆(OH)₆ ⁸- triangle. The [V₆B₂₀O₃₈(OH)₁₂]⁴- clusters are separated in the solid state by Rb⁺ cations. Magnetic susceptibility and valence sum calculations indicate that all six of the vanadium atoms in the cluster are in the 4+ oxidation state.
