Synthesis and Characterization of a Binuclear Copper(II)-dipyriamethyrin Complex: [Cu 2 (dipyriamethyrin)(μ 2 -1,1-acetato) 2 ]

The reaction between dipyriamethyrin and copper(II) acetate [Cu(OAc) ] afforded what is, to our knowledge, the first transition metal-dipyriamethyrin complex. Molecular and electronic characterization of this binuclear Cu(II) complex via EPR, UV-vis, and single crystal X-ray diffraction analysis rev...

Description
Summary:The reaction between dipyriamethyrin and copper(II) acetate [Cu(OAc) ] afforded what is, to our knowledge, the first transition metal-dipyriamethyrin complex. Molecular and electronic characterization of this binuclear Cu(II) complex via EPR, UV-vis, and single crystal X-ray diffraction analysis revealed marked differences between the present constructs and previously reported binuclear copper(II) hexaphyrin species. UV-vis titration analyses provided evidence for a homotropic positive allosteric effect, wherein the binuclear species is formed without significant intermediacy of a monomeric complex.
