Syntheses, crystal structures, photo-physical properties, antioxidant and antifungal activities of Mg(II) 4,4′-bipyridine and Mg(II) pyrazine complexes of the 5,10,15,20 tetrakis(4-bromophenyl)porphyrin

This study concerns the synthesis of 5,10,15,20-tetrakis(4-bromophenyl)porphyrin (H2TBrPP)-based magnesium (II) complexes involving 4,4 '-bipyridine (4,4 '-bpy) and pyrazine (pyz) ligand, for [Mg(TBrPP)(4,4 '-bpy)] (1) and [Mg(TBrPP)(pyz)2] (2), respectively. New complexes 1 and 2 were characterized by single crystal X-ray diffraction, elemental analysis, infrared and nuclear magnetic resonance spectroscopies. The photo-physical properties were investigated by UV-visible absorption and emission spectroscopies. These new magnesium(II) complexes exhibit promising antifungal and antioxidant activities.

Automated summary

This study synthesized magnesium (II) complexes based on H2TBrPP, which exhibited promising photo-physical properties and potential antifungal and antioxidant activities.
