Abstract: Three Mn<superscript>II</superscript> complexes, named Mn<subscript>2</subscript>(HATNA)<subscript>2</subscript>(CH<subscript>3</subscript>OH)<subscript>4</subscript> (1), {[Mn<subscript>3</subscript>(ATNA)<subscript>2</subscript>(DMF)<subscript>2</subscript>(H<subscript>2</subscript>O)<subscript>2</subscript>]·0.5DMF·0.5H<subscript>2</subscript>O}<subscript>n</subscript> (2, DMF = N,N-dimethylformamide), and {[Mn<subscript>6</subscript>(ATNA)<subscript>4</subscript>(H<subscript>2</subscript>O)<subscript>10</subscript>]·8DMSO·2.5H<subscript>2</subscript>O}<subscript>n</subscript> (3, DMSO = dimethyl sulphoxide), were successfully synthesized by the reaction of the ligand azotetrazole-3-hydroxy-2-naphthoic acid (H<subscript>3</subscript>ATNA) and Mn(CH<subscript>3</subscript>COO)<subscript>2</subscript> in CH<subscript>3</subscript>OH, DMF, and DMSO, respectively. A binuclear structure was found for complex 1, with the two Mn(II) ions doubly bridged through N–N linkers from the two tetrazole rings. Both 2 and 3 displayed one-dimensional structures. Magnetic studies show that antiferromagnetic interactions of Mn(II) ions existed in complexes 1–3. All the complexes exhibited luminescence emission peaks at room temperature. [ABSTRACT FROM AUTHOR]
