Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Reactions of Hpymtza [Hpymtza = 5‐(2‐pyrimidyl)tetrazole‐1‐acetic acid] with MnCl₂<bold>·</bold>4H₂O under different pH conditions, afforded the complexes [Mn(pymtza)₂(H₂O)₄] (<bold>1</bold>) and [Mn₂(pymtza)₂Cl₂(EtOH)]<bold>·</bold>H₂O (<bold>2</bold>). The compounds were structurally characterized by elemental analysis, IR spectroscopy and single‐crystal X‐ray diffraction. Compound <bold>1</bold> shows a mononuclear structure, whereas complex <bold>2</bold> has a 1D chain structure. In compound <bold>1</bold>, the pymtza ligand only acts in a monodentate manner to coordinate to one central Mn^II atom by one carboxylate atom, In <bold>2</bold>, pymtza acts as tetradentate ligand to connect three Mn^II ions. Compounds <bold>1</bold> and <bold>2</bold> display 3D networks by hydrogen bonding interactions. Furthermore, the luminescence properties of Hpymtza as well as compounds <bold>1</bold> and <bold>2</bold> were investigated at room temperature in the solid state.</p> </abstract>
