Syntheses, structures, and fluorescent properties of two new d10-metal coordination polymers containing 1-((benzotriazol-1-yl)methyl)-1-H-1,2,4-triazole ligand

Two new coordination polymers formulated as {[Zn(bdic)(bmt)H2O] · 0.5H2O} n (1) and {[Cd(bdic)(bmt)(H2O)2] · 2H2O} n (2) (H2bdic = 1,3-benzenedicarboxylic acid, bmt = 1-((benzotriazol-1-yl)methyl)-1-H-1,2,4-triazole) have been synthesized and characterized by elemental analysis, IR, and single-crystal X-ray diffraction. Both coordination polymers exhibit 1-D chain structure where bmt is unidentate and bdic2− bridging. In 1, bmt hangs at two sides of the main chain, whereas bmt hangs at one side of the main chain in 2. Fluorescent properties have also been determined.
