The homometallic 3-D coordination intercatenated polymer, [Ca(H2L)(H2O)]·2H2O, has been obtained by assembling a dianionic ligand H2L2− = 4,4′-sulfonylbis(phenyl)bis(oxamate) with calcium(II) ions. We also describe the crystalline structure of the proligand, H4L, and the structure of its diethylester precursor, H2Et2L, and the importance of intermolecular interactions to the supramolecular architecture.
通过将二阴离子配体 H2L2- = 4,4′-磺酰双(苯基)双(草氨酸)与钙(II)离子组装在一起,获得了同金属三维配位互缠聚合物 [Ca(H2L)(H2O)]-2H2O。我们还描述了原配体 H4L 的晶体结构及其二乙酯前体 H2Et2L 的结构,以及分子间相互作用对超分子结构的重要性。
