Abstract
A series of C-functionalized β-ketoimine compounds at the terminal methyl groups of the β-ketoimine precursor LphH2 (Lph = C6H4[NC(Me)CHC(Me)O]2) were prepared. This convenient transformation was realized via straightforward double alkylation on the terminal Cα of a novel bis-dianionic β-ketoiminate lithium complex [Lph'Li4(THF)4]2 (Lph' = C6H4[NC(Me)CHC(O)CH2]2) followed by hydrolysis.

Abstract
The solid complexes of Pd(II) and Cd(II) with N,N/bis(salicylaldehyde)4,5-dimethyl-1,2-phenylenediamine (H2L(1)), and N,N/bis(salicylaldehyde)4,5-dichloro-1,2-phenylenediamine (H2L(2)) have been synthesized and characterized by several techniques using elemental analysis (CHN), FT-IR, (1)H NMR, UV-Vis spectra and thermal analysis. Elemental analysis data proved 1:1 stoichiometry for the reported complexes while spectroscopic data indicated square planar and octahedral geometries for Pd(II) and Cd(II) complexes, respectively. The prepared ligands, Pd(II) and Cd(II) complexes exhibited intraligand (π-π(∗)) fluorescence and can potentially serve as photoactive materials. Thermal behavior of the complexes was studied and kinetic parameters were determined by Coats-Redfern method. Both the ligands and their complexes have been screened for antimicrobial activities.

Abstract
4,4′-Diaminobiphenyl reacts with 2,4-pentanedione in absolute ethanol in a molar ratio 1 : 2 to form mainly the product of [1 + 2] condensation, 4,4′-(biphenyl-4,4′-diyldinitrilo)dipentan-2-one (H2L). The Schiff base was used as tetradentate chelating ligand to coordinate CoII and NiII chlorides leading to complexes where the ratio of metal ligand was found to be 2 : 1 or 2 : 2. All the synthesized products were characterized by elemental analysis, infrared, electronic, and mass spectroscopy, 1H NMR, and DSC. The electrochemical behaviour of the ligand and its complexes in DMF is also investigated.

Abstract
The NiII ion in the one-dimensional title complex, {[Ni2(C4H2O4)(OH)2(C10H9N3)2]·2H2O}n, has a distorted square-pyramidal coordination environment formed by three O atoms from two bridging hydroxide groups and one carboxylate group of the fumarate ligand and two pyridine N atoms from a di-2-pyridylamine (dpa) ligand. Two hydroxide groups link adjacent metal centers, forming a centrosymmetric four-membered [Ni2(OH)2] ring. In the crystal structure, the H atoms of the bridging hydroxide groups form intermolecular hydrogen bonds to both water molecules. These are further linked to the uncoordinated O atoms of the carboxylate groups and the NH group of a dpa ligand to generate a three-dimensional network from the chains of the coordination polymer.

Abstract
Based on a combined theoretical-experimental study, we propose that substituted m-phenylene ligands (m-N-Phi-N) can act as tuneable strong ferromagnetic couplers connecting Cu(II) ions; a new complex presenting that bridge with J close to +15 cm(-1) has been suggested and synthesized.
