Two cadmium(II) coordination polymers, namely, [Cd3( m-phth)2(atz)2] n ( 1) ( m-phth = m-phthalate and atz = 3-amino-1,2,4-triazolate) and [Cd(atphth)(H2O)] n ( 2) (atphth = 2-aminoterephthalate), were synthesized and structurally characterized. Compound 1 features a three-dimensional (3D) pillared framework based on two-dimensional (2D) cadmium-benzenedicarboxylate ladders pillared by the triazolate ligands. Compound 2 has a 3D framework constructed from 2D cadmium-benzenedicarboxylate layers, which are further linked by Cd-N bonds between the cadmium ions and amino groups of the atphth2- ligands of the adjacent layers to form the final 3D structure. Compounds 1 and 2 exhibit solid-state photoluminescence with emission maxima at 448 and 470 nm, respectively. [ABSTRACT FROM AUTHOR]
