A new three-dimensional (3D) hybrid compound [Cu-4(EGTA)(2)(H2O)(4)Cu-2(H2O)(8)][SiW12O40]center dot 14H(2)O (1), [EGTA = ethyleneglycol-bis-(2-aminoethylether)-tetra acetic acid], was conventionally synthesized and characterized by elemental analysis. IR, TG, and single crystal X-ray diffraction. In 1, the square inorganic layers formed by the coordination of tungstosilicate anions to copper ions are supported by Cu-4(EGTA)(2) metallamacrocyclic cations, giving a unique 3D framework with alpha-Po topology. Additionally, luminescent and magnetic properties of 1 are investigated in the solid state.
