Dinuclear μ‐Phenoxo and μ‐Hydroxo Bridged Copper Complexes Exhibiting Oxidation of Phenols and Isoelectronic Compounds: Cytotoxicity and Evidences for Cellular Apoptosis

“…Upon fitting, the coupling constant ( J Cu‐Cu ) values that are obtained are –208.00 cm ‐1 , –204.47 cm ‐1 , and –205.16 cm ‐1 for complexes 1 , 2 and 3 , respectively. The values obtained were quite similar to the magnetic coupling constant values reported by Massoud and co‐workers …”

Synthesis, characterisation and ROP catalytic evaluation of Cu(II) complexes bearing 2,2ʹ-diphenylglycine-derived moieties

“…This values is compatible with the [(CuBr 2 ) 2 (Dpg) 2 Cu(EtOH) 4 ] unit. Finally, the magnetic moment of 2 was found to be 3.0 µ B , which is consistent with previously reported Cu-based complexes [16] .…”

“…this value is compatible with the molecular mass of [(CuCl) 2 (Dpg) 2 (EtOH) 2 ]. Finally, the magnetic moment (m) was found to be 2.5 µ B , which is consistent with the values typically observed for Cu(II) complexes [16] .…”

A computational study of structural and magnetic properties of bi- and trinuclear Cu(II) complexes with extremely long Cu---Cu distances

“…We also plan to extend our studies for more complicated systems of tetranuclear Cu(II) complexes, particularly for complexes with porphyrin and tetraoxa [8]circulene sheets as the macrocyclic polydentate ligands [51][52][53].…”

“…between the corresponding singly-occupied molecular orbitals (so-called SOMOs), determines the type of coupling -ferromagnetic when the ground electronic state corresponds to the high-spin configuration with parallel orientation of electronic spins and antiferromagnetic when the ground electronic state is characterized by the low total spin with antiparallel orientation of the electronic spins [1,2]. Nowadays, the most prevalent and well studied organometallic magnetic systems are dinuclear copper(II) complexes with different types of linkers between the ligand-coordinated magnetic centers (-Hal-, [6,7], -OH-, [4,6,8,9] -OR-, [10][11][12][13] CN-, [14] -N^N-, [8,9,15] -N^O- [16,17] etc.). These complexes can demonstrate a variety of coupling types from strongly antiferomagnetic (exchange coupling constant J CuCu is strongly negative up to -1000 cm -1 ) [4][5][6] to moderately ferromagnetic (J CuCu is positive, typically of order 100 cm -1 ) [10,18].…”
