Syntheses, Structures, and Photoluminescence of Two Three‐dimensional Cadmium Coordination Polymers with Benzene­dicarboxylate Ligands

Abstract

AbstractTwo 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.
