Beschreibung:
Two new metal complexes involving Schiff base ligands, namely, [Pd(L1)2] (1) and [Zn(L2)2] (2), [HL1: 2,4-dibromo-6-((E)-(mesitylimino)methyl)phenol andHL2: 2-((E)-(2,6-diisopropylphenylimino)methyl)-4,6-dibromophenol], have been solvothermally synthesized and characterized by elemental analysis, IR-spectroscopy, thermogravimetric analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. Both1and2are mononuclear cyclometalated complexes with square planar and tetrahedral coordination geometry, respectively.1and2display photoluminescence in the solid state at 298 K (fluorescence lifetimesτ= 5.521 μs at 508 nm for1;τ= 3.697 μs at 506 nm for2). These Schiff base ligands and their metal complexes have been screened for antibacterial activity against several bacteria strains, and the results are compared with the activity of penicillin. Moreover, the Suzuki reaction of 4-bromoanisole with phenylboronic acid by1has also been studied.
