Crystal structure, physicochemical properties, Hirshfeld surface analysis and antibacterial activity assays of transition metal complexes of 6-methoxyquinoline

摘要: Five monomeric complexes of Co(II), Cu(II), Ni(II), Zn(II) and Ag(I) with 6-methoxyquinoline (6-MeOQ) as ligand have been prepared, their crystal structures determined by single X-ray diffractions. The Ni(II) are formulated M(6-MeOQ)2Cl2, completing MN2Cl2 coordination spheres. On the other hand, Co(II) compounds ionic formulae [Ag(6-MeOQ)2]+ NO3− H(6-MeOQ)+[Co(6-MeOQ)Cl3]− (where H(6-MeOQ)+ is protonated ligand). Hirshfeld surface analysis was employed to study intermolecular interactions in lattices from these studies it found that π-stacking contacts play an important role. Besides, characterized FTIR, UV-visible emission spectroscopies. singlet oxygen production fluorescence quantum yields were measured for all employing steady-state methodologies. Finally, antibacterial activity screened against both Gram-positive Gram-negative bacteria.
