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 bdic^2? 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.
