Cyanide-bridged trinuclear Mn-III-Fe-III assembly: Crystal structure, magnetic and photoluminescence behavior
Özet
A trinuclear cyanide-bridged Mn-III-Fe-III compound, [NEt4][Mn(3,5-ClL)(2)(MeOH)](2)Fe(CN)(6)], [3,5-ClLH2 = N, N'-bis(3,5-chlorosalicylidenato)-1,2-diamino propane)], 1, has been characterized by X-ray analyses, magnetic and photoluminescence measurements. The structure assumes a two-dimensional network consisting of Mn-NC-Fe-CN-Mn (Fe1-C19-N4 = 175.9(3)degrees, C19-N4-Mn1 = 145.5 (3)degrees). The magnetic properties of this compound indicate antiferromagnetic coupling between low-spin Fe(III) and high-spin Mn(III) through the cyanide bridges. Furthermore, solid state photoluminescence properties of complex 1 have been investigated at room temperature. (C) 2016 Elsevier B.V. All rights reserved.
