Abstract

Abstract: Reactions of cadmium(II) salts with 3-amino-5-methylthio-1H-1, 2, 4-triazole (Hamstz) afforded two cadmium(II) coordination polymers, [Cd2 (amstz)2 Cl2 ]n (1 ) and [Cd2 (amstz)2 (NO3 )2 ]n (2 ). Compounds1 and2 feature 2-D layered structures based on the dinuclear [Cd2 (amstz)2 ] subunits. The cadmium coordination polyhedra are tetrahedral and tetragonal pyramidal in1 and2, respectively, due to the presence of different coordinated anions, Cl − and NO3 − . Compounds1 and2 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.
