Abstract: | In the title three‐dimensional coordination polymer, Sr(4‐CPOA)(H2O)]n (where 4‐CPOA2? is the 4‐carboxylatophenoxyacetate dianion, C9H6O5), each SrII atom displays a bicapped triangular prismatic configuration, defined by five carboxyl and one ether O atom from five different 4‐CPOA2? ligands, as well as two water molecules. The SrII atoms are covalently linked by 4‐CPOA2? ligands and water molecules, giving rise to a three‐dimensional open framework. In previously studied polymers of this type, the 4‐CPOA2? ligand shows a variety of binding modes to metal ions, from mono‐ to pentadentate. In the present SrII complex, a novel hexadentate bridging mode is observed. |
