Abstract

A new organic–inorganic hybrid (H2en)2[[Cu(en)2]AsIIIAsVMoVI9O34]·6H2O (1), containing a 1-D helical chain based on the trivacant monocapped Keggin arsenomolybdate and the copper complex linker {[Cu(en)2][AsIIIAsVMoVI9O34]}n4n− (en = ethylenediamine), has been synthesized and characterized by IR spectra, TG analyses, single-crystal X-ray diffraction, and high-resolution electrospray ionization mass spectrometry (ESI-MS). Large voids are observed and a 1-D chain containing repeated (H2O)8 water units from lattice water molecules is formed along the a axis in the crystal structure. The high-resolution ESI-MS shows that the intact framework [Cu(en)2][AsIIIAsVMoVI9O34]4− exists in solution.
