A novel composite complex constructed from Keggin-type tungstoborate and copper, [Cu(En)(2)(H2O)][Cu(En)(2)](2)H-3[BW11.75Cu0.25O40] center dot 3.75H(2)O (I), where En is ethylenediamine, has been synthesized hydrothermally and characterized by elemental analysis, IR, XPS, TGA, and single-crystal X-ray diffraction. The crystal structure of I consists of one Keggin polyoxoanion [BW11.75Cu0.25O40](6-), one cation [Cu(En)(2)(H2O)](+), two cations [Cu(En)(2)](+), three protons, and 3.75 lattice water molecules. Compound I crystallizes in the orthorhombic, space group Pbca, a = 21.5438(18), b = 20.6591(18), c = 26.052(2) angstrom, V = 11595.2(17) angstrom(3), Z = 8, rho = 3.968 g/cm(3), F(000) = 12322, mu = 24.476 mm(-1), R = 0.0306 and wR = 0.0666.
