Abstract2-[(pyridin-2-ylmethylidene)amino]-6-aminopyridine (L1), 2-[(2-furylmethylene)]phenylenediamine (L2) and their Mn(II) and Pd(II) complexes have been synthesized as potential photoactive materials, and their structures were elucidated using a variety of physicochemical techniques. The molar conductance data reveal that all complexes are nonionic in nature. Theoretical calculations were computed using the density functional theory, where the B3LYP functional was employed. The experimental results and the calculated parameters revealed a square planar and octahedral geometry around Pd(II) and Mn(II), respectively, in which the ligands coordinate to the metal ions as a bidentate manner. The thermal decomposition of the complexes has been studied. The catalytic activity of the complexes toward hydrogen peroxide decomposition reaction was investigated at 35 and 55 °C. In addition, the synthesized ligands, in comparison with their metal complexes, were screened for their antibacterial activity.
