Complex 1 features a one-dimensional （l-D） parallel ribbon-like structure. There are extensive hydrogen-bonding interactions involving coordinated water molecules and free carboxylate oxygen atoms. In addition, π-π interactions via benzoic multicarboxylate ligands are discussed. These non-covalent interactions lead to the formation of a 3-D framework.展开更多
