Complexes of copper (II) acetate with nicotinamide: preparation, characterization and fungicidal activity; crystal structures of [Cu2 (O2CCH3)4 (nia)] and [Cu2 (O2CCH3)4 (nia)2]

New Dimeric Copper(II) Complex [Cu(5‐MeOsal)2(μ‐nia)(H2O)]2 with Magnetic Exchange Interactions through H‐Bonds

“…Nicotinamide (also known as a niacin derivative or vitamin B 3 ) is a nitrogen donor ligand that has been used in the treatment of various skin diseases (atopic eczema, [1,2] psoriasis and skin cancer [3][4][5] ), and the biological activity of its copper complexes have also been studied. [6] In addition, the biological activity of different salicylic acid derivatives and their copper(II) complexes is well known. [7][8][9][10] Meanwhile, salicylatocopper(II) complexes that contain nicotinamide are rarely studied in spite of their possible structural diversities.…”

Syntheses and Characterizations of Copper Complexes: Interaction of Copper Acetate Dihydrate With 4,4´-Bipyridine

“…Several studies of copper(II) acetate complexes with nitrogen ligands, such as pyridine, aminopyrimidine, bipyridyl, and nicotinamide, have been reported. Instead of forcing dissociation of the dinuclearCu 2 (CH 3 COO) 4 units, these ligands simply replace bound water molecules, causing only small changes in the CuCu distances ( Figure 1) [1][2][3][4]. Similar behavior has been found with polymeric ligands containing nitrogen functional groups [5,6].…”

Voltammetric Study and Thermodynamic Parameters of [Zn_L-Amino Acidate_Vitamin-PP] Complexes vis-à-vis Kinetics of Electrode Reaction

“…The same is evident from pK values of L-amino-acids [19]. In the case of vitamin-PP, N-atom of pyridine group and O-atom of amide group may take part in bond formation with Zn (II), forming a six-membered ring [20]. It is clear from the values of stability constants of the complexes that vitamin-PP and amino acids used either singly or simultaneously might be effective to reduce the toxicity of metal in vivo.…”
