| Abstract: | A one-dimensional coordination polymer Cu(en)2]2Cu(en)2(H2O)]2{Cu(en)2]2Cu2Si2W22O78]}·4.5H2O (en=ethylenediamine), which represents the first example of one-dimensional organic-inorganic hybrid based on the bimolecular Keggin polyoxometalates {Cu(en)2]2Cu2Si2W22O78]}8− has been hydrothermally synthesized and characterized by elemental analyses, IR, TG and single crystal X-ray diffraction. Crystal data: C24H85Cu8N24O84.5Si2W22, monoclinic, P21/c, a=18.8126(3), b=23.0896(4), c=26.0711(4) Å, β=96.3790(10)°, V=11254.5(3) Å3, T=293(2) K; Z=4, μ=23.983 mm−1, R1=0.0628, wR2=0.1210 I>2σ], R1=0.0854, wR2=0.1285 (all data ). |
