A new porous crystal of [Cu(enMe)2]4 [H5VIV18O42(Cl)]8H2O constructed from metal-oxo cluster building blocks was hydrothermally synthesized and characterized by elemental analysis, IR, EPR and single-crystal X-ray diffraction. The compound crystallizes in tetragonal system, space group P4/nnc with a = 15.0034(3), c = 18.8149(3) ? V = 4235.27(14) ?, Z = 2, Dc = 2.055 g/cm3, Mr = 2620.74, m = 2.988 mm-1, F(000) = 2608, R = 0.0766, wR = 0.2118, S = 1.193, (Dr)max = 0.969×103 and (Dr)min = 0.454×103 e/3. The structure is a three-dimensional framework linked alternatively by [H5VIV18O42(Cl)]8- polyoxoanions and [Cu(enMe)2] complex cations.
