Three novel inorganic鈭抩rganic hybrid arsenomolybdates constructed from monocapped trivacant [AsIIIAsVMo9O34]6鈭?/sup> fragments with [Cu(en)2]2+ or [Cu(dap)2]2+ linkers, [Cu(en)2H2O]2{[Cu(en)2][Cu(en)2AsIIIAsVMo9O34]}2路4H2O (1), (H2en)1.5[Cu(en)(Hen)][AsIIIAsVMo9O34]路2H2O (2) (en = ethylenediamine), and [Cu(dap)2]4[Cu(dap)2(H2O)][Cu(dap)2(AsIIIAsVMo9O34)2]路2H2O (3) (dap = 1,2-diaminopropane), have been successfully synthesized under hydrothermal conditions and structurally characterized by elemental analyses, IR spectra, single-crystal X-ray diffraction, and thermogravimetric (TG) analysis. Single-crystal structural analyses indicate that 1鈭?b>3 all contain the peculiar monocapped trivacant [AsIIIAsVMo9O34]6鈭?/sup> subunit derived from the infrequent trivacant Keggin [A-伪-AsVMo9O34]9鈭?/sup> fragment with a capping {AsO3} group. Notably, 1鈭?b>3 represent rare inorganic鈭抩rganic hybrid heteropolymolybdate (HPM) containing [AsIIIAsVMo9O34]6鈭?/sup> subunits, which display the assembly from a zero-dimensional sandwich-type dimer, one-dimensional chain, to a two-dimensional layer by the [Cu(en)2]2+ or [Cu(dap)2]2+ linkers. Surface photovoltage spectroscopy (SPS) and electric field induced surface photovoltage spectroscopy (EFISPS) measurements for 1鈭?b>3 indicate that only 3 has the n-type semiconductor characteristic.
