A fascinating 3D pillared-layer structure, namely [Cd-3(bpea)(2)(trz)(2)(H2O)(2)]center dot DMF (1), has been isolated under hydrothermal condition by reaction of cadmium salt, biphenylethene-4,4'-dicarboxylic acid (bpea) and 1,2,4-triazole (Htrz). Compound 1 presents an unusual self-penetrating network displaying uninodal seven-connected {4(14).5.6(6)) topology with trinuclear cadmium clusters as seven-connected nodes, which exhibited exceptional resistance to acid/base aqueous solutions. Furthermore, solvent-dependent luminescence properties of 1 were investigated, and the results showed that 1 could serve as a potential luminescent sensor in detecting traces of the target species, such as toluene and nitrobenzene.
