A one-dimensional coordination polymer [Cu(en)(2)](2)[Cu(en)(2)(H2O)](2) {[Cu(en)(2)](2)[Cu2Si2W22O78]}center dot 4.5H(2)O (en=ethylenediamine), which represents the first example of one-dimensional organic-inorganic hybrid based on the bimolecular Keggin polyoxometalates {[Cu(en)(2)](2)[Cu2Si2W22O78]}(-8) has been hydrothermally synthesized and characterized by elemental analyses, IR, TG and single crystal X-ray diffraction. Crystal data: C24H85Cu8N24O84.5Si2W22 monoclinic, P2(1)/c, a = 18.8126(3), b = 23.0896(4), c = 26.0711(4) A, beta = 96.3 790(10)degrees, V = 11254.5(3) A(3), T = 293(2) K; Z = 4, mu = 23.98 3 mm(-1), R-1 = 0. 0628, wR(2) = 0. 1210 [1 > 2 sigma a], R-1= 0. 0.0854, wR(2) = 0.1285 (all data).
