Abstract
Two new metal-organic coordination polymers with l,5-dinitronaphthalene-3, 7-dicarboxylate (NNDC), [Cu2(NNDC)2(DMF), 1.8(DMSO)2.2(H2O)2]-H2O (1) and [Mn3(NNDC)3(DMSO)4]DMSO (2) have been synthesized under solvothermal conditions and characterized by single crystal X-ray diffraction and Thermogravimetric Analysis (TGA). The structure of compound 1 consists of one-dimensional chains with copper ions being linked by the dicarboxylate ligands. The coordination chains are associated into ladder-like double chains through O-H&O hydrogen bonds and Tt-Jt interactions, and the ladders are packed in a cross fashion through further n-n interactions to give the three-dimensional structure. The Mn(II) compound exhibits a 3D framework with the peu topology, in which [Mn3(COO) e] clusters as octahedral secondary building blocks are linked by the naphthalene spacers. Magnetic analyses were carried out based on both temperature- and field-dependent data, consistently suggesting relatively weak antiferromagnetic interactions within the carboxylate bridged [Mn 3(COO)6] cluster.
