A three-dimensional inorganic/organic hybrid material, [Ni2(4,4′-bipy)3(H2O)2V4O12]·2.5H2O

The title compound, poly[[[diaqua(μ-4,4'-bipyridyl)dinickel(II)]-bis(μ-4,4'-bipyridyl)-di-μ-hexaoxodivanadate(2-)] 2.5-hydrate], [Ni 2 (V 2 O 6 ) 2 (C 10 H 8 N 2 ) 3 (H 2 O) 2 ].2.5H 2 O, has been prepared hydrothermally and characterized by elemental analyses, IR spectroscopy and single-crystal X-ray diffraction. The structure consists of [V 2 O 6 ], [Ni(4,4'-bipy) 4 O 2 ] and [Ni(H 2 O) 2 (4,4'-bipy) 2 O 2 ] polyhedra, and water of crystallization. The Ni atoms and one bipyridyl group lie on centres of symmetry.
