A new three-dimensional (3D) hybrid compound [Cu4(EGTA)2(H2O)4Cu2(H2O)8][SiW12O40]·14H2O (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 Cu4(EGTA)2 metallamacrocyclic cations, giving a unique 3D framework with α-Po topology. Additionally, luminescent and magnetic properties of 1 are investigated in the solid state.
Graphical abstractA new hybrid compound [Cu4(EGTA)2(H2O)4Cu2(H2O)8][SiW12O40]·14H2O (1) was conventionally synthesized and characterized, in which the square inorganic layers formed by the coordination of tungstosilicate anions to copper ions are supported by bidentate Cu4(EGTA)2 metallamacrocyclic cations giving a unique 3D framework with α-Po topology.Figure optionsDownload full-size imageDownload as PowerPoint slideResearch highlights► A unique 3D α-Po framework is formed by SiW12–Cu layers and Cu4(EGTA)2 cations. ► The use of the multidentate multicarboxyl flexible ligand EGTA is important and effective. ► The luminescent and magnetic properties of compound 1 have been studied.
