Abstract:
In the title three-dimensional coordination polymer, [Sr(4-CPOA)(H2O)](n) (where 4-CPOA2- is the 4-carboxylatophenoxyacetate dianion, C9H6O5), each Sr(II) 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 Sr(II) 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 Sr(II) complex, a novel hexadentate bridging mode is observed.

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
