| Abstract: In the presence of N ancillary ligands, imidazole (ImH) and 5-(4-pyridyl)tetrazole (4-PT), treatment of 3,4-pyrazoledicarboxylic acid (H3pdc) with corresponding Mn (Ⅱ)/Zn(Ⅱ) metal salts afforded two complexes, [Mn(Hpdc) (ImH)(H2O)]n (1) and [Zn(Hpdc)(4-PT)(H2O)3]·2H2O (2). In the 1D coordination polymer 1 and mononuclear complex 2 , the Hpdc2- ligand adopted μ2-κ∶O,N; κ∶O',O″ coordination mode and O,N-chelating mode, respectively, while the ImH and 4-PT ligands in 1 and 2 both acted as a monodentate ligand. In 1, in the influence of intermolecular N—H…O and O—H…O hydrogen bonds, the 1D coordination chains are packed into a 3D supramolecular structure. In 2, in the function of intermolecular O—H…O and O—H…N hydrogen bonds, the adjacent mononuclear components [Zn(Hpdc)(4-PT)(H2O)3] are packed into 2D structures, then these 2D layers and the lattice water molecules are interlinked and generated a 3D supramolecular architecture. Moreover, the luminescent properties of complexes 1 and 2 as well as the electrochemical property of 1 were also investigated. |
