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

Abstract

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.
