A 1,2,4-Triazole-based Polynuclear Mixed-valence Mn^IIMn^III Complex: Synthesis, Characterization, and Magnetic Property

Research output: Contribution to journal › Article › peer-review

Abstract

A mixed-valence Mn complex {[Mn^IIMn^III(HL)₂(4,4′-bpy)(H₂O)₂]·(ClO₄)(DMF)₃(4,4′-bpy)_0.5}_n (1) [H₂L = 3-(2-phenol)-5-(pyridin-2-yl)-1,2,4-triazole] was synthesized and characterized by X-ray single-crystal structure analysis and magnetic susceptibility. Single-crystal X-ray analysis revealed that complex 1 has a dinuclear core, in which adjacent central Mn^III atoms are linked by 4,4′-bipyridine to form an infinite one-dimensional (1D) molecular configuration. According to the Mn surrounding bond lengths and bond valence sum (BVS) calculations, we demonstrated that the Mn atom coordinated to the pyridine N atoms is in the +2 oxidation state, while another Mn atom coordinated to the phenolic oxygen atoms is in the +3 oxidation state. Magnetic susceptibility data of the complex 1 indicate that the ferromagnetic interaction dominates in this complex.
