Article Citation - WoS: 5Citation - Scopus: 5Hydrothermal Synthesis and Characterization of One Dimensional Chain Structures of Monolacunary Keggin Polyoxoanions Substituted With Copper(Elsevier Ltd., 2015) Eanes, Mehtap; Önen, Banu; McMillen, Colin D.Two novel polymeric polyoxometallates constructed from transition metal substituted heteropolytungstates, [(4,4’bpyH2)2(4,4’bpyH)][PCuW11O39]·H2O (1), and [(4,4’bpyH2)(pyH)3][PCuW11O39]·2H2O (2), (4,4’bpy = 4,4’bipyridine, py = pyridine) have been synthesized under hydrothermal conditions and characterized by IR, TGA, single crystal X-ray diffraction and magnetic measurements. The product formation showed a high sensitivity toward experimental factors including pH and stirring. Compounds 1 crystallizes in the monoclinic space group P2(1)/n with a = 13.503(3) Å, b = 26.726(5) Å, c = 15.168(3) Å, = 99.61(3)° and Z=4. The second compound also crystallizes in space group P2(1)/n, but with a = 13.519(3) Å, b = 20.431(4) Å, c =18.655(4) Å, = 96.52(3)° and Z=4. Compound 1 exhibits a zigzag chain structure, while compound 2 exhibits a straight chain structure. Compound 2 is the first example of a polyoxometallate containing 1D chains of transitionmetal- substituted heteropolytungstate designed with two significantly different organic units as the countercations. The Cu2+ ions in 1 exhibit paramagnetic behavior.Article Citation - WoS: 4Citation - Scopus: 4Hydrothermal Synthesis and Characterization of a Novel Supramolecular Hybrid Based on Keggin and Cu(i) Complex(Elsevier, 2013) Eanes, Mehtap; Önen, BanuA novel inorganic-organic hybrid molecule, [Cu(4,4′bipyH)3(4,4bipy)][HPW12O40]2.12H2O (1), has been hydrothermally synthesized and characterized by IR spectra, TG and single crystal X-ray diffraction analyses. Structural analysis reveals that the novel compound 1 composed of two Kegging polyoxoanion connected with Cu complex fragment forming a big molecule that extends in 3D via hydrogen bonding.
