Ferromagnetic Coupling in a New Copper(II) Schiff Base Complex with Cubane Core: Structure, Magnetic Properties, DFT Study and Catalytic Activity

Abstract

Ioning in distortions: Severe ionic distortions of phenyl‐substituted hydrocarbon anions are observed on coordination to Na+ or K+ ions. Alkali‐metal salts of 1,2‐diphenylbenzene (see picture: Na green, O red) and 1,2,3‐triphenylbenzene dianions are prepared by reduction, structurally characterized, and analyzed by density functional and natural bond order calculations. The reduction and subsequent cation coordination of the phenylbenzene ions dramatically distorts the structures of the hydrocarbon skeletons.

Synthesis, characterization, crystal structure and predicting the second-order optical nonlinearity of a new dicobalt(III) complex with Schiff base ligand

“…These compounds form stable and variety complexes with the majority of transition metal ions that exhibit various electronic and structure characteristics [5][6][7][8][9]. Therefore, the research area containing the coordination compounds with azomethine ligands as main characters is widely expansive especially due to their potential interest roles in various interdisciplinary fields such as: structural features [10,11], efficient different catalytic processes in various organic reactions [12][13][14], models of the metal ion coordination sites in metalloproteins or enzymes at bioinorganic chemistry [15][16][17], magnetochemistry [18][19][20], corrosion inhibitors [21] and nonlinear optical materials [22][23][24]. Second-Order NLO organic materials such as Schiff base compounds have recently attracted attention owing to their potential applications in computers, optical communication and medical imaging [25,26].…”

Copper(II) and nickel(II) complexes of tetradentate Schiff base ligand: UV-Vis and FT-IR spectra and DFT calculation of electronic, vibrational and nonlinear optical properties

“…The fast developing in the synthesis of Schiff base ligands is raised from their enough facile preparation and wide variety of applications such as industrial, optical devices, biological, analytical, medical and catalytical investigations [4][5][6][7]. The Schiff base ligands are suitable candidates in coordination chemistry due to the various applications of their complexes like nonlinear optical (NLO) properties, catalytic activity and metallo-protein models in bioinorganic chemistry [8][9][10].…”

Polynuclear Complexes with Alkoxo and Phenoxo Bridges from In Situ Generated Hydroxy‐Rich Schiff Base Ligands: Syntheses, Structures, and Magnetic Properties

“…[5,6] Thus, hydroxy-rich ligands containing a reactive amino moiety are significant for the ability of forming polydentate Schiff base ligands that can bridge metal ions and mediate the interactions between the metal centers. [8] 1-aminoglycerol contains two alkoxyl groups and a reactive amino group, which may be employed to synthesize multidentate Schiff base ligands with multiple endogenous chelating and bridging moieties.
