Poly[μ-aqua-μ4-terephthalato-strontium]

Abstract

In the title compound, [Sr(C8H4O4)(H 2O)]n, the SrII atom exhibits coordination number eight, with six O atoms from four carboxylate groups (two bidentate and two monodentate) of terephthalate ligands and two water O atoms. The SrO8 polyhedra are linked into inorganic chains by sharing three coplanar O atoms. These inorganic chains are extended along the b axis to form layers in the ab plane by O -C -O linking. Parallel layers are connected by terephthalic groups, forming a three-dimensional framework. O -H⋯O hydrogen-bonding interactions are observed.
