A novel organic-inorganic hybrid germanotungstate [ Ni (dien) (H2O)3]2[Ni(Hdien)2]·{[Ni(dien)]2 Ni4(H2O)2(GeW9 O34)2}·10H2 O (1)(dien=diethylenetrimine) was synthesized under hydrothermal conditions and characterized by IR spectroscopy, TGA, elemental analysis, energy-dispersive X-ray spectroscopy and single-crystal X-ray structural analysis. Crystal data for compound 1: triclinic system, space group P(-1),a=1.1937(3) nm, b = 1.4323 (3) nm, c = 1.6394 (4) nm, α =93.424(2)°, β= 96.058(3)°, γ =109. 758(4)°, V= 2. 6094( 1 ) nm3, Z = 1. X-ray crystallographic study reveals that compound 1 was built from [ Ni (dien) ]2+ decorated Weakley-type sandwich polyoxoanion linked by [ Ni (Hdien) 2 ] 4 + cations to form a 1 D linear structure, which further stacks to form 3D network.
