A novel strontium carboxylate-sulfonate coordination polymer, [Sr(HSIP)(H2O)(3)](n)center dot nH(2)O (1) (NaH2SIP = 5-sulfoisophthalic monosodium salt) has been synthesized by hydrothermal reaction. It was characterized by X-ray single crystal diffraction, infrared spectroscopy, elemental and thermogravimetric analysis. Each strontium atom is eight-coordinate with a distorted bicapped trigonal prismatic arrangement. The whole HSIP2- ligand acts as a eta(5)mu(4) bridge to generate three-fold interpenetrated CdSO4-type network structure, which is constructed from the left- and right-handed helixes paralleled to each other bridged by the HSIP2- ligands. The luminescence spectrum indicates an emission maximum at 459 nm. Compound 1 shows a second harmonic generation (SHG) response that is 4 times that of KH2PO4.
