A twofold interpenetrating two-dimensional zinc(II) coordination polymer: synthesis, crystal structure and physical properties.

ABSTRACT

A novel twofold interpenetrating two-dimensional (2D) ZnII coordination framework, poly[[(µ-1,3-bis(2-methyl-1H-imidazol-1-yl)benzene-κ2N3N3)(µ-naphthalene-2,6-dicarboxylato-κ2O2O6)zinc(II)] dimethylformamide monosolvate], {[Zn(C12H6O4)(C14H14N4)]·C3H7NO}n or {[Zn(1,3-BMIB)(NDC)]·DMF}n (I), where H2NDC is naphthalene-2,6-dicarboxylic acid, 1,3-BMIB is 1,3-bis(2-methyl-1H-imidazol-1-yl)benzene and DMF is dimethylformamide, was prepared and characterized through IR spectroscopy, elemental analysis, thermal analysis and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis revealed that (I) exhibits an unusual twofold interpenetrating 2D network. In addition, it displays strong fluorescence emissions and a high photocatalytic activity for the degradation of Rhodamine B (RhB) under UV-light irradiation.
