Molecular Supertetrahedron Decorated with Exposed Sulfonate Groups Built from Mixed-Valence Tetranuclear Fe33+Fe2+(mu(3)-O)(mu(3)-SO4)(3)(-CO2)(3) Clusters
We present the synthesis and characterization of a novel metal-organic molecular solid using the ligand 4,8-disulfonaphthalene-2,6-dicarboxylic acid. The solid features a sulfonated, isolated supertetrahedra, [Fe16O4(SO4)(12)(L2)(6)], built from mixed-valence [Fe33+Fe2+(mu(3)-O)(mu(3)-SO4)(3)(-CO2)(3)] clusters.
