Two novel zinc(II) coordination polymers constructed from in situ amidation ligands

Two novel coordination compounds, [Zn(Hbimh) (H2O)]·H2O (1) and [Zn(Hbimh)]·(4,4ʹ-bpy)0.5 (2) (H3bimh = benzimidazole-5,6-hydrazide, 4,4ʹ-bpy = 4,4ʹ-bipyridine), have been prepared from the hydrothermal in situ amidation cyclization reactions of H3bimdc (H3bimdc = benzimidazole-5,6-dicarboxylic acid...

Summary:Two novel coordination compounds, [Zn(Hbimh) (H2O)]·H2O (1) and [Zn(Hbimh)]·(4,4ʹ-bpy)0.5 (2) (H3bimh = benzimidazole-5,6-hydrazide, 4,4ʹ-bpy = 4,4ʹ-bipyridine), have been prepared from the hydrothermal in situ amidation cyclization reactions of H3bimdc (H3bimdc = benzimidazole-5,6-dicarboxylic acid) and hydrazine hydrate (N2H4·H2O). Compound 1 exhibits a one-dimensional (1D) hexagon channel structure. Compound 2 is a three-dimensional (3D) framework structure, with 4,4ʹ-bpy fill the channels. We also obtained the ligand H3bimh. The compounds were characterized by IR, PXRD, TGA and elemental analysis. The fluorescence properties in the solid state at room temperature were also investigated. [Display omitted] •In situ reaction between N2H4·H2O and H3bimdc were proceeded for the first time.•Compound 1 exhibits a 1D hexagon channel structure.•Compound 2 is a 3D framework structure, with 4,4ʹ-bpy fill the channels.•The fluorescence properties were investigated.
