Abstract: A novel organic-inorganic hybrid germanotungstate [Ni(dien)(H2O)3]2[Ni(Hdien)2] -{[Ni(dien)]2Ni4(H2O)2(GeW9O34)2}?10H2O (1) (dien = diethylenetrimine) has been synthesized under hydrothermal conditions and characterized by IR spectroscopy, TGA, elemental analysis, Energy-Dispersive X-ray Spectroscopy (EDS) and single-crystal X-ray structural analysis. Crystal data for 1: Triclinic, P-1, a = 11.937(3) ?, b = 14.323(3) ?, c = 16.394(4) ?, α = 93.424(2)o, β = 96.058(3)o, γ = 109.758(4)o, V = 2609.4(10) ?3, Z = 1. X-ray crystallographic study reveals that 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 stack 3-D network.
