  Four novel isostructural coordination polymers {[M(H′L)2(H2O)2]·2DMF} [M=Zn(II), Cd(II), Mn(II) and Co(II)] built using a nitrogen and oxygen donor azo ligand: Crystal structures and fluorescence studies

  摘要：

  When the ligand HH'L was treated with different transition metal salts at room temperature, four new isostructural coordination polymers, {[Zn(H'L)(2)(H2O)(2)]center dot 2DMF}(n) (1), {[Cd(H'L)(2)(H2O)(2)]center dot 2DMF}(n) (2), {[Mn(H'L)(2)(H2O)(2)]center dot 2DMF}(n) (3), and {[Co(H'L)(2)(H2O)(2)]center dot 2DMF}(n) (4) (HH'L = 2-hydroxy-5-(pyridin-4-ylazo)-benzoic acid) were formed. These polymers were characterized by IR spectroscopy, elemental analysis, powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA), in addition to X-ray crystallography. X-ray single crystal studies revealed that 1-4 are 1D coordination polymers that are further extended by weak interactions to afford 3D coordination polymers. All the complexes show high thermal stability after losing coordinated and lattice solvent molecules in the temperature range 80-200 degrees C. Upon excitation at 344 nm, complexes 1-4 exhibit solid-state luminescence at room temperature. (c) 2013 Elsevier Ltd. All rights reserved.
