China *e-mail: wyapan2008@163.com Received December 2, 2015 structural analysis reveals that I shows a simple 1D linear array based on [Co2(COO)2] SBUs, II and III exhibit 2D layer structue and 2D networks with 1D open channel based on [Co2(COO)2], [CuN2O2] and [Cu2(COO)4] SBUs, respectively. <...> Interestingly, such 1D or 2D motifs in I–III possess the recognition sites of hydrogen bonding and/or weak π–π stacking, which generate the resultant 3D architectures. <...> Additionally, the solid state properties such as thermal stabilities and the magnetic properties of I–III are also investigated. <...> Keywords: 1,3-di(3',5'-dicarboxylphenyl)benzene acid, Co(II)/Cu(II)-coordination polymers, crystal structure, magnetic properties DOI: 10.7868/S0132344X17020098 INTRODUCTION of coordination polymers have provoked significant interest owing to their diversified structural topologies and potential applications in luminescence, magnetism, gas adsorption/separation and catalysis [1–4]. <...> As is known, the selection of organic linkages is one of the most important aspects, and the configuration, flexibility, substitute and coordination modes of organic ligands play critical effects on the resulting structures [5–7]. <...> The systematic studies on the coordination modes of ligands may bring new understanding of the construction of coordination polymers. <...> Meanwhile, 1,3-di(3',5'-dicarboxylphenyl)benzene acid (H4Ddpb), as a member of multidentate O-donor ligands, has a wide variety of coordination modes, deriving by partially <...>
