The rational selection of ligands is vitally important in the construction of coordination complexes. Two novel Zn II complexes, namely bis(acetato‐κ O )bis[1‐(1 H ‐benzotriazol‐1‐ylmethyl)‐2‐propyl‐1 H ‐imidazole‐κ N 3 ]zinc(II) monohydrate, [Zn(C 13 H 15 N 5 ) 2 (C 2 H 3 O 2 ) 2 ]·H 2 O, ( 1 ), and bis(azido‐κ N 1 )bis[1‐(1 H ‐benzotriazol‐1‐ylmethyl)‐2‐propyl‐1 H ‐imidazole‐κ N 3 ]zinc(II), [Zn(C 13 H 15 N 5 ) 2 (N 3 ) 2 ], ( 2 ), constructed from the asymmetric multidentate imidazole ligand, have been synthesized under mild conditions and characterized by elemental analyses, IR spectroscopy and single‐crystal X‐ray diffraction analysis. Both complexes exhibit a three‐dimensional supramolecular network directed by different intermolecular interactions between discrete mononuclear units. The complexes were also investigated by fluorescence and thermal analyses. The experimental results show that ( 1 ) is a promising fluorescence sensor for detecting Fe 3+ ions and ( 2 ) is effective as an accelerator of the thermal decomposition of ammonium perchlorate.
