The synthesis and characterization of the novel systems [Zn₂(H₂N(CH₂)₂NH₂)₅][{Zn(H₂N(CH₂)₂NH₂)₂}₂V₁₈O₄₂(H₂O)]·9H₂O (1), [Cd₂(H₂N(CH₂)₂NH₂)₅][{Cd(H₂N(CH₂)₂NH₂)₂}₂V₁₈O₄₂(Br)]·9H₂O (2), and [Zn₂(H₂N(CH₂)₂NH₂)₅][{Zn(H₂N(CH₂)₂NH₂)₂}₂V₁₈O₄₂(Cl)]·9H₂O (3) have been described. These materials represent a new class of solids that have beenprepared by combining conventional coordination compounds with spherical polyoxovanadate clusters. Theisomorphous structures of these hybrid solids consist of two-dimensional arrays of container cluster molecules{V₁₈O₄₂(X)} (X = H₂O, Br^-, Cl^-) interlinked by the transition metal complex moieties {M(H₂N(CH₂)₂NH₂)₂} (M =Zn, Cd). These compounds contain an unprecedented complex cation, [M₂(H₂N(CH₂)₂NH₂)₅]⁴⁺.
