    Abstract

    Four new coordination polymers were obtained by employing polycarboxylato spacers and cationic copper(II) complexes as nodes: ∞2[Cu3(trim)2(NH3)6(H2O)3] (1); ∞1[Cu(tmen)(dhtp)] (2), ∞1[Cu(tmen)(hitp)(H2O)] (3), ∞1[Cu(tmen)(nitp)] (4). (H3trim = trimesic acid, H2dhtp = 2,5-dihydroxy-terephthalic acid; H2hitp = 5-hydroxy-isophthalic acid, H2nitp = 5-nitro-isophthalic acid; tmen = N,N,N′,N′-tetramethyl-ethylenediamine). The crystal structures of the four compounds have been solved. Compound 1 consists of 2D coordination polymers with heart-shaped meshes, while compounds 2-4 contain infinite zigzag chains. The role of the hydrogen bond interactions in sustaining the supramolecular solid-state architectures in compounds 1 and 3 is discussed. The cryomagnetic investigation of compounds 1, 2, and 4 reveals antiferromagnetic interactions between the copper ions. © 2008 Elsevier Ltd. All rights reserved.
