A new coordination polymer, [Zn2SO4(atz)2(H2O)2]·(H2O)4 (1) (Hatz = 1H-3-amino-1,2,4-triazole) has been synthesized using zinc sulfate and an asymmetric 3-substituted triazole ligand at room temperature. X-ray analysis reveals that complex 1 shows a 3D-framework containing Zn2(atz)2(H2O)2SO4 subunits, which display a 6-coordinated unimodal pcu topological network. Further, complex 1 exhibits purple fluorescence with an emission maximum at 405 nm in the solid state at room temperature.
