CRYSTAL STRUCTURE AND FLUORESCENCE OF A 1D ZINC(II) COORDINATION POLYMER BASED ON A SEMI-RIGID bis(BENZIMIDAZOLE) LIGAND

Abstract

A new Zn(II) coordination polymer, {[Zn(npht)(L) 0.5 (H 2 O)]H 2 O} n (L = 1,4-bis(2-methylbenzimidazol-1-ylmethyl)benzene, H 2 npht = 3-nitrophthalic acid) has been hydrothermally synthesized and characterized by elemental analysis, IR, XRPD, and single-crystal X-ray diffraction. The Zinc(II) coordination compound exhibits a 1D linear chain, which is further assembled into a 2D supramolecular layer via two modes of classial hydrogen bonding interactions. The fluorescence properties and thermal stability of the complex have been investigated in the solid state.
