Two 2-dimensional cadmium(II) coordination polymers with 3-amino-5-methylthio-1,2,4-triazolate ligand
No full text<p>Reactions of cadmium(II) salts with 3-amino-5-methylthio-1H-1,2,4-triazole (Hamstz) afforded two cadmium(II) coordination polymers, [Cd<sub>2</sub>(amstz)<sub>2</sub>Cl<sub>2</sub>]<sub>n</sub> (<b>1</b>) and [Cd<sub>2</sub>(amstz)<sub>2</sub>(NO<sub>3</sub>)<sub>2</sub>]<sub>n</sub> (<b>2</b>). Compounds <b>1</b> and <b>2</b> feature 2-D layered structures based on the dinuclear [Cd<sub>2</sub>(amstz)<sub>2</sub>] subunits. The cadmium coordination polyhedra are tetrahedral and tetragonal pyramidal in <b>1</b> and <b>2</b>, respectively, due to the presence of different coordinated anions, Cl<sup>−</sup> and NO<sub>3</sub><sup>−</sup>. Compounds <b>1</b> and <b>2</b> exhibit photoluminescence emission with maxima at 620 and 621 nm upon excitation at 470 and 472 nm, respectively, which can be attributed to the ligand-to-metal charge transfer emssion.</p
