An organic–inorganic hybrid 1D helical chain arsenomolybdate {[Cu(en)2][Cu(en)(H2O)][(Cu(en)2(H2O)] [AsIIIAsVMo9O34)]} · 2H2O (1) (en = ethylenediamine) has been hydrothermally synthesized and characterized by elemental analyses, IR, UV and CD spectrum, powder X-ray diffraction, TG-DTA and single-crystal X-ray diffraction. The asymmetric unit of 1 consists of a monocapped trivacant Keggin [AsIIIAsVMo9O34]6 − subunit, a pendant [Cu(en)2(H2O)]2 + cation, a pendant [Cu(en)(H2O)]2 + cation, one bridging [Cu(en)2]2 + cation and two lattice water molecules. It should be noted that 1 illustrates a one-dimensional (1D) helical chain assembled by {[Cu(en)(H2O)][(Cu(en)2(H2O)][AsIIIAsVMo9O34)]}2 − clusters and [Cu(en)2]2 + linkers.
A new organic–inorganic hybrid arsenomolybdate {[Cu(en)2][Cu(en)(H2O)][(Cu(en)2(H2O)] [AsIIIAsVMo9O34)]} · 2H2O has been hydrothermally synthesized, which displays a 1D helical chain assembled from {[Cu(en)(H2O)][(Cu(en)2(H2O)][AsIIIAsVMo9O34)]}2 − clusters and [Cu(en)2]2 + linkers.Figure optionsDownload as PowerPoint slideHighlights
► Reports on TM-containing lacunary arsenomolybdate fragments are rather rare.
► A novel organic–inorganic arsenomolybdate hybrid was hydrothermally obtained.
► The first hybrid assembled from [AsIIIAsVMo9O34)]} clusters and {Cu(en)2} linkers
► The hybrid displays a unique 1D helical chain.
