Crystal structure and fluorescence of a 1D zinc(II) coordination polymer based on a semi-rigid bis(benzimidazole) ligand

A new Zn(II) coordination polymer, {[Zn(npht)(L)(0.5)(H2O)]aEuro cent H2O} (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
