A new Sr(Ⅱ) complex, [Sr(Hsip)(H2O)](1, NaH2sip = 5-sulfoisophthalic acid monosodium), has been synthesized by solvothermal reaction of Sr CO3 and NaH2sip at 120 ℃, and characterized by single-crystal X-ray diffraction studies, elemental analysis and FT-IR. Singlecrystal X-ray diffraction reveals that compound 1 has a 3D architecture, and there is only one crystallographically independent Sr(Ⅱ) ion in 1. The coordination geometry of Sr(Ⅱ) is a distorted tetragonal anti-prism. The whole Hsip2- ligand performs a μ6-coordination model. In the solid state, complex 1 shows luminescence with the maximum emission intensity at 417 nm upon excitation at 320 nm. Thermal stability of complex 1 was also investigated.
