ABSTRACT
A new double salt of nickel(II) complexes, formulated as, [Ni(bipy)(H2O)4][Ni(H2O)6][Ni(pydc)2]2 ⢠6H2O, (1), (pydc = pyridine-2,6-dicarboxylate anion, bipy = 2,2'-bipyridine) has been hydrothermally synthesized. Complex was characterized by FT-IR spectroscopy, elemental analysis and X-ray diffraction studies. The compound 1 consists of [Ni(H2O)6]2+, [Ni(bipy)(H2O)4]2+, two symmetry-independent anionic complexes [Ni(pydc)2]2- and six co-crystallized water molecules. In the crystal structure of compound 1, the formation of extensive O-H O hydrogen bonds between uncoordinated water molecules and cationic or anionic complexes play important roles in stabilizing the corresponding lattice and formation of 3-dimensional networks.
