Synthesis and characterization of a novel one-dimensional Zn(II) coordination polymer based on in situ generated 1-methyl-2-(3H-[1,2,3]triazol-4-yl)-1H-benzoimidazole

One novel 1D chain of {[Zn2(L)3(H2O)(NO3)]·2.5H2O}n (HL = 1-methyl-2-(3H-[1, 2, 3]triazol-4-yl)-1H-benzoimidazole) has been hydrothermally constructed from in situ generated 1-methyl-2-(3H-[1, 2, 3]triazol-4-yl)-1H-benzoimidazole ligand at 160 °C. Compound 1 exhibits a 1D butterfly-like chain architecture, which is further assembled into a 3D supermolecular network by interchain hydrogen bonds. TGA studies show that compound 1 is highly thermally stable. The fluorescent property in the solid state is also explored, and the emission spectrum shows a blue shift of 62 nm compared with that of HL, which may be assigned to ligand-to-metal charge transfer.
