A new organic-inorganic hybrid based on the crescent-shaped polyoxoanion [H _6SiNb _(18)O _(54)] ~(8-) and copper-organic cations

摘要

A new organic-inorganic hybrid, [Cu(en) _2] _3{[Cu(en) _2][H _6SiNb _(18)O _(54)]}·22H _2O (1, en = ethylenediamine) containing the crescent-shaped polyoxoanion [H _6SiNb _(18)O _(54)] ~(8-) and copper-organic cations has been successfully synthesized, and elemental analyses, IR spectra, thermogravimetric analyses and single-crystal X-ray diffraction were investigated.
