在标题化合物[Sr(C8H4O4)(H2O)]n中，SrII原子具有配位数8，其中6个O原子来自对苯二甲酸酯配体的4个羧基(2个双齿和2个单齿)，2个水O原子。通过共享三个共面的O原子，SrO8多面体连接成无机链。这些无机链沿着b轴延伸，通过O-C-O连接在ab平面上形成层。平行层由对苯二甲酸基团连接，形成三维骨架。观察到O-H、⋯、O氢键相互作用。
In the title compound, [Sr(C8H4O4)(H2O)]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.
