Abstract
A new metal-organic framework of Sr(II) with phenylmalonic acid, {[Sr(PMA)(H2O)].H2O}n (SPMA) has been prepared by gel diffusion technique. SXRD data show that the crystal belongs to the orthorhombic space group Pbca. In the crystal structure, the phenylmalonate ligand adopts monodentate, bis-monodentate and bidentate coordination modes with the Sr(II) ions. The Sr-phenylmalonate units extend three dimensionally forming a network structure. Intermolecular hydrogen bonding further stabilizes the crystal system. The compound exhibits strong luminescence emission at 290 nm upon excitation at 240 nm. Sensing property of the title compound towards Fe3+ ion is also investigated.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
