Two pillared-layer architectures constructed from copper molybdate sheets and linear organonitrogen ligands.

In this article, we report the syntheses and structures of two new inorganic–organic hybrid copper molybdates with organonitrogen ligands, [Cu2(bpe)(Mo2O8)] · 3H2O (1) (bpe = 1,2-bis(4-pyridyl)ethene) and [{Cu(4,4′-bpy)}2(Mo2O8)] (2) (bpy = 4,4′-bipyridine). Elemental analyses, IR spectra, EPR spectra, XPS spectra, TG analyses and single crystal X-ray diffraction were used to characterize these compounds. The structure of 1 exhibits a pillared-layer framework built up from unusual bimetallic two-dimensional sheets pillared by linear bpe ligands. Compound 2 features a pillared-layer structure constructed from copper molybdate 4,8-net sheets connected by 4,4′-bpy ligands. [ABSTRACT FROM AUTHOR]
