Cyclometalated Complexes

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.

The asymmetric unit of the title complex, [Pd(C15H13FNO)2], contains one half of the molecule with the PdIIcation lying on an inversion centre and is coordinated by the bidentate Schiff base anion. The geometry around the cationic PdIIcentre is distorted square planar, chelated by the imine N- and phenolate O-donor atoms of the two Schiff base ligands. The N- and O-donor atoms of the two ligands are mutuallytrans, with Pd—N and Pd—O bond lengths of 2.028 (2) and 1.9770 (18) Å, respectively. The fluorophenyl ring is tilted away from the coordination plane and makes a dihedral angle of 66.2 (2)° with the phenolate ring. In the crystal, molecules are linked into chains along the [101] direction by weak C—H...O hydrogen bonds. Weak π–π interactions with centroid–centroid distances of 4.079 (2) Å stack the molecules alongc.

Tridentate Schiff Base

New complexes with the Schiff base ligand derived from S-benzyldithiocarbazate (NH2—NH—CSSCH2C6H5) have been prepared and characterized by elemental analyses, magnetic, conductometric, ir, and electronic spectral studies. The tridentate ONS Schiff base S-benzyl-β-N-(phenyl, phenylhydroxymethyl)methylenedithiocarbazate gave mono-ligand complexes with Ni(II) and Cu(II) having the general formula [MligandX] (M = Ni(II) and Cu(II); X = NO3, Cl, Br, NCS). A proposed square-planar structure for the nickel complexes is supported by magnetic and spectral data. A square-planar structure is also suggested for Cu(II) complexes. The ir results give evidence of the different bondings present in the complexes.
