Three MnII complexes, named Mn2(HATNA)2(CH3OH)4 (1), {[Mn3(ATNA)2(DMF)2(H2O)2]·0.5DMF·0.5H2O}n (2, DMF = N,N-dimethylformamide), {Mn6(ATNA)4(H2O)10]·8DMSO·2.5H2O}n (3, DMSO = dimethyl sulphoxide) were successfully synthesized from the reaction of the ligand azotetrazole-3-hydroxy-2-naphthoic acid (H3ATNA) and Mn(CH3COO)2 in CH3OH, DMF and DMSO, respectively. A binuclear structure was found for complex 1, in which the two Mn(II) ions are doubly bridged through N-N linkers from two tetrazole rings. Both 2 and 3 display one-dimensional structures. Magnetic studies show that there exist antiferromagnetic interactions of Mn(II) ions in complexes 1-3. All the complexes exhibit luminescent emission peaks at room temperature.
