Abstract
A mixed-valence Mn complex {[MnIIMnIII(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 MnIII 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.
