Syntheses, structure and electrochemical characterization of homo- and heterodinuclear copper complexes with compartmental ligands

Distortion Isomerism of Cu(II) Chloride Adducts with Bis(2-benzimidazolyl)ethane. Synthesis, Characterization, X-ray Structures and Spectroscopy of Four Different Isomers

“…The coordination chemistry of the heterocyclic azoles acting as ligands in copper(II) compounds in the context of modelling biological systems has gained much interest in the past decades [1][2][3][4]. In this respect bis(2-benzimidazoles) have received much attention for their wide-ranging antivirus activity [5,6], their importance in selective ionexchange resins [7,8] and the possibility to form supramolecular aggregates with d 10 metal ions [9].…”

“…(in which Hb = EtOH or MeOH and x = 1/2 or 1). The X-ray crystal structure has been solved from four different compounds, the green a-[CuCl 2 dbz](C 2 H 5 OH) 1 (4). The characterization was further done by spectroscopic methods and EPR.…”

Synthesis, spectroscopic characterization and antibacterial activities of three Schiff bases derived from dehydroacetic acid with various substituted anilines

“…The azomethine linkage of the Schiff bases is responsible for various antibacterial, antifungal, herbicidal, clinical and analytical activities [5,6]. Schiff base ligands that contain strong donor sites like phenoxo oxygen atoms and imine nitrogen atoms are brilliant for analytical and biological applications [7,8]. Dehydroacetic acid (dha = 3-acetyl-4-hydroxy-6-methyl-2H-pyran-2-one), and compounds derived from it are very important class of compounds for various organic synthesis [9].…”

Interplay of Magnetic Exchange Interactions and NiSNi Bond Angles in Polynuclear Nickel(II) Complexes

“…[10][11][12] Macrocyclic ligands are often employed as supporting ligands as their complexes are more stable than those of their acyclic counterparts. In addition the metal ions are fixed in close proximity and can be arranged in almost any topology which has important implications for the metal-metal interactions [13,14] and the binuclear metal reactivity. [15] We are interested in the coordination chemistry of the hexaaza-dithiophenolate ligand H2L 1 and its various derivatives.…”
