Anderson-like alkoxo-polyoxovanadate clusters serving as unprecedented second building units to construct metal–organic polyhedra

Abstract

Unprecedented Anderson-like alkoxo-polyoxovanadate [V₆O₆(OCH₃)₉(μ₆-SO₄)(COO)₃]²⁻ polyanions can serve as 3-connected second building units (SBUs) that assemble with dicarboxylate or tricarboxylate ligands to form a new family of metal organic tetrahedrons of V₄E₆ and V₄F₄ type (V = vertex, E = edge, and F = face). To our knowledge, this alkoxo-polyoxovanadate-based SBU is the first ever reported.
