A novel centrosymmetric dinuclear Cd(II) complex [CdL (CH3COO)]2 (1) has been synthesized by the reaction of Cd(CH3COO)2·2H2O with a Schiff base ligand HL [HL = (E)-2-((pyridin-2-yl)methyleneamino)ben

Two monomeric copper complexes [Cu(Pymab)(CCl3COO)(H2O)].H2O (1) and [Cu(Pymaib)(H2O)Cl]2 (2) were synthesized by reacting copper (II) trichloroacetate and copper(II) chloride with the monobasic tridentate Schiff-Base ligands (HPymab = (E)-2-((pyridine-2-yl)methyleneamino)benzoic acid and HPymaib = 4-iodo-2-{(E)-[(pyridin-2-yl) methyleneamino}benzoic acid) and characterized by elemental analysis, IR, UV–Vis, mass spectrometry, CV and single crystal XRD analysis. Both complexes are monomeric in the solid state and in the solution as well. For both complexes, single crystal XRD indicates a distorted square pyramidal coordination geometry of the metal atoms. Both 1 and 2 behave as effective catalysts towards the oxidation of 3,5-di-tert-butyl catechol to the corresponding quinone derivative in aerial oxygen. The reactions follow the Michaelis-Menten enzymatic reaction kinetics with (kcat) values of 1452 h?1 and 1458 h?1 respectively in DMSO and 1590 h?1 and 1636 h?1 in THF respectively. In the solid state both compounds participate in halogen bonding interactions that have been studied using DFT calculations and the molecular electrostatic potential (MEP) and the noncovalent interaction plot index (NCI plot) computational tools.

Two copper(II) polymeric complexes {[Cu(HPymat)(MeOH)](NO 3)}n (1) and {[Cu4(Pymab)4(H 2O)4](NO3)4} (2) were synthesized with the carboxylate-containing Schiff-base ligands HPymat- and Pymab- [H2Pymat = (E)-2-(1-(pyridin-2-yl)methyleneamino) terephthalic acid, HPymab = (E)-2-((pyridine-2-yl)methyleneamino)benzoic acid]. Complex 1 is a one-dimensional Cu(II) cationic polymeric complex containing free protonated carboxylic groups and nitrate anions as counterions. Complex 2 is a zero-dimensional tetranuclear cationic Cu(II) complex containing nitrate anions as counterions. Complex 1 shows rhombic electron paramagnetic resonance (EPR) spectra in the solid state at room temperature (RT) and 77 K and tetragonal EPR spectra in dimethyl sulfoxide (DMSO) and dimethylformamide (DMF) and inverse EPR spectrum in CH3CN. Complex 2 shows rhombic EPR spectra in the solid state at RT and 77 K. But complex 2 shows tetragonal spectra in DMSO, DMF, and CH3CN. Thermogravimetric analysis was also performed for both complexes 1 and 2. Mean-square displacement amplitude analysis was carried out to detect librational disorder along the metal-ligand bonds in crystal structures.
