Diastereoselective Synthesis and X-ray Structure of New Stable Dicyano (8aRS,10SR,11SR)-9,9-dicyano-10-aryl-11-benzoyl -8a,9,10,11-tetrahydropyrrolo[1,2-a][1,10]phenanthrolines

Antituberculosis, Antifungal and Photoluminescence Studies on a Mn(II)–Neocuproine Complex

The complex [Mn(Me2phen)(H2O)3(MeOH)][NO3]2, (Me2phen = 2,9-dimethyl-1,10-phenanthroline, neocuproine) has been prepared. Structural studies show that the [Mn (Me2phen) (H2O)3(MeOH)] cation is a six coordinate octahedral species with bidentate Me2phen and monodentate water and methanol ligands. The water molecules are hydrogen bonded to a Me2phen free ligand, which is co-crystallised in a position adjacent to the Mn complex. Face-to-face π···π stacking interactions between coordinated and free Me2phen ligand molecules generate an efficient parallel packing system in the complex, which also shows antituberculosis and antifungal activity. Photoluminescence properties are also reported.
