Two new isostructural lanthanide(III) coordination polymers based on an unreported zwitterionic ligand, namely, [Ln(ox)(L)]n (ox = oxalate, HL = N,N' -dipropionic acid imidazolium, Ln = Eu or La), are synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, infrared spectroscopy, powder X-ray diffraction, and thermogravimetric analysis. The fluorescence properties of the europium coordination polymer are investigated. In addition, the europium-based coordination polymer is utilized for specific sensing of UO22+ ions, showing high selectivity, a fast response time (8 min) and high sensitivity with noticeable quenching (K sv = 6.19 × 104 M−1) and limit of detection of 1.95 µM.

Compound 3-amino-N-[4-chloro-3-(trifluoromethyl)phenyl]-4-morpholino-1H-indazole-1-carboxamide has been synthesised by condensation of 1-chloro-4-isocyanato-2-(trifluoromethyl)benzene with 4-morpholino-1H-indazol-3-amine, which was prepared from 2,6-difluorobenzonitrile by amination with morpholine and then cyclisation with hydrazine hydrate. The crystal structure of the title compound was determined. In addition, the compound possesses a distinct inhibitory capacity against proliferation of the A549 and BGC-823 cancer cell lines.
