A novel calcium complex, [Ca-4(SIP)(3)(phen)(8)(H2O)(6)]center dot(Hphen)center dot(phen)center dot 27H(2)O (1) (NaH2SIP = 5-sulfoisophthalic monosodium salt, phen = 1,10-phenanthroline), has been synthesized by hydrothermal reaction at 160 degrees C. It was characterized by X-ray single-crystal diffraction, infrared spectroscopy, and elemental and thermogravimetric analysis. Complex 1 features an approximate U-shaped structure, where the tetranuclear calcium ions are bridged by tridentate and tetradentate SIP3- ligands, together with free 1H-protonated 1,10-phenanthroline balancing the charge. Each calcium ion is eight-coordinated showing distorted bicapped trigonal prism geometry. The luminescence spectrum indicates an emission maximum at 463 nm. Complex 1 shows a second harmonic generation response that is three times that of KH2PO4.
