The structure of single crystal of the polyoxotungstate salt Na_(10){(PW_9O_(34))_2Ni_4(H_2O)2}·26H_2O ( Na_(10)Ni4O96P2W18H56, Mr=5371.96) has been determined by X-ray diffraction (MoK(). Crystal data: P21/n, a=11.898(2), b=16.629(4), c=21.413(4) ?, ( = 100.59(1)o, V= 4164.5(1) ?3, Z=2, Dc = 4.284g/cm3, F(000) = 4704, ( =2.5847cm-1, final R = 0.0344, and wR= 0.0804 for 5830 independent reflections. Two B-(-PW_9O_(34)9- units in the compound are linked via a set of four coplanar Ni2+ atoms, which also carry H_2O ligands. The NiO6 octahedra in each centrosymmetric anion are all tetragonally elongated with their long axes parallel.
