Cyanide-bridged trinuclear MnIII–FeIII assembly: Crystal structure, magnetic and photoluminescence behavior

• 2D trans-cyano-bridged MnIII–FeIII complex was synthesized.
• Crystal structure of complex 1 has been described.
• Photoluminescence properties and magnetic behavior of complex 1 have been studied.

A trinuclear cyanide-bridged MnIII–FeIII compound, [NEt4][Mn(3,5-ClL)2(MeOH)]2Fe(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)°, C19–N4–Mn1 = 145.5 (3)°). 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.

2D trans-cyano-bridged MnIII–FeIII complex has been synthesized and characterized single crystal X-ray diffraction. The photoluminescence and magnetic properties of complex were also discussed.Figure optionsDownload as PowerPoint slide
