【 摘 要 】

Studies on the novel coordination polymers by self-assembly of multidentate ligands and transition metal ions are of great interest and importance due to their structural diversity and potential applications in catalysts, separation, hydrogen storage, and molecular recognition.1−5 To date, a large number of 1-D, 2-D and 3-D extended frameworks have been prepared from the combination of metal ions with linear and/or nonlinear multidentate ligands.6 Coordination polymers based on hexamethylenetetramine (hmt) have been extensively studied due to their versatile ligation modes from monodentate to bridging bi-, tri- and tetradentate.7 When hmt is combined with carboxylate which can act as monodentate, bridging, and even chelating ligands through their donor atoms, higher dimensional frameworks are also made possible through non-covalent bonding such as hydrogen bond.8 Therefore, we have decided to explore the system of Cd2+ metal ions with mixed ligands such as linear 4-hydroxybenzoic acid (hbzH) and tetrahedral hexamethylenetetramine. 4-hydroxybenzoate anion (hbz), deprotonated form of hbzH, is linear and a remarkably versatile building block for the construction of coordination polymers due to its versatile ligation modes and possible hydrogen bond formation. Furthermore, the facile variety of coordination configurations around a Cd2+ metal ion can offer much opportunities for us to design and synthesize interesting coordination polymers with various architectures and dimensions for exploring new functional materials. Here, we present the synthesis and crystal structure of a 2-D layer compound of [Cd(hmt)2(hbz)2(H2O)] constructed through the hydrogen bonding.
