Abstract

•Two novel luminescent Cadmium(II) frameworks have been isolated.•1 contains novel infinite triple Cd-(trz)-Cd bridges.•2 presents a rare I2O0 type framework.•The solid-state photo-luminescent spectra of organic ligand L and 1-2 also have been measured.

Using the 4-substituted-1,2,4-triazole derivate ligand 4-p-tolyl-1,2,4-triazole (L), two novel luminescent Cadmium(II) frameworks, namely {[Cd(μ2-L)3]·(NO3)2·L}n (1) and [Cd1.5(μ2-L)(μ2-Br)2(μ3-Br)]n (2) have been isolated under hydrothermal conditions. The structural analysis reveals that 1 presents a one-dimensional (1D) chain structural motif containing novel infinite triple Cd-(trz)-Cd bridges (triply trz-bridged M–M species). While 2 presents a rare I2O0 type framework, in which the infinite 2D Cd–Br–Cd inorganic connectivity with a 4-connected Kagome topology can be observed. The FT-IR, PXRD and thermal stabilities of 1–2 have investigated. The solid-state photo-luminescent spectra of organic ligand L and 1–2 also have been measured indicating strong emission bands.
