Three Mn(II) supramolecular coordination complexes containing carboxylate–tetrazolate ligands

Three novel complexes [Mn(atza)2(H2O)4] (1), [Mn(nptza)2(CH3OH)4] (2), and [Mn(a4-ptz)2(H2O)2]n · 2nH2O] (3) [atza = 5-aminotetrazole-1-acetato, nptza = 5-[(4-nitryl)phenyl] tetrazole-1-acetato, a4-ptz = 5-[N-acetato(4-pyridyl)] tetrazole] containing carboxylate–tetrazolate ligands have been synthesized and characterized by element analysis. X-ray crystallography shows that complexes 1 and 2 both contain mononuclear structure. The complex 3 is a 1D polymeric chain structure. Compounds 1–3 are self-assembled to form supramolecular structures through hydrogen bonds interactions.
