Syntheses and structural characterization of three coordination polymers of Cd(II), Zn(II) and Pb(II) with the “V” shape ligand 4,4′-[isopropylidenebis(p-phenyleneoxy)]diacetic acid
摘要:
Three new inorganic-organic coordination polymers based on a "V" shape linking unit 4,4'-[isopropylidenebis(p-phenyleneoxy)]diaceticacid (H(2)L) and Cd(II), Zn(II) and Pb(II) ions, [Cd(L)(H(2)O)(2)](n) (1), [Zn(2)(L)(3)-(H(2)O)(6)center dot 6H(2)O](n) (2) and [Pb(2)Na(2)(L)(3)(DMF)(4)(H(2)O)(2)center dot 2H(2)O](n), (3), have been prepared and structurally characterized by single-crystal X-ray diffraction analysis. Complex 1 is a 1 D zig-zag chain coordination polymer, which is connected by strong hydrogen-bond interactions to result in a 3D network. In complex 2, an infinite 2D (6, 3) network with large hexagonal cavities was created. The whole 2D structure is a noninter-penetrating framework stacked by hydrogen-bonding interactions. Complex 3 is a novel 3D heterometallic coordination polymer, which possesses three different types of isolated channels. (C) 2009 Elsevier B.V. All rights reserved.
