<p>A hetero-metal organic framework, [NaSr(HTiron)(H<sub>2</sub>O)<sub>5</sub>]·H<sub>2</sub>O (<b>1</b>) (Na<sub>2</sub>H<sub>2</sub>Tiron = 4,5-dihydroxy-1,3-benzenedisulfonic acid disodium), has been synthesized under hydrothermal condition. The framework was characterized by elemental analysis, FT-IR spectroscopy, UV–Vis spectroscopy, thermal analysis, and single-crystal X-ray diffraction. It features a 3-D network structure with (4<sup>2</sup>,12<sup>4</sup>)(4<sup>5</sup>,6<sup>4</sup>,8)<sub>2</sub>(4)<sub>2</sub> topology, constructed by HTiron<sup>3−</sup> ligands. Compared with the ligand, the photoluminescence emission of <b>1</b> bathochromically shifts and shows emission maximum at 497 nm at room temperature.</p>
