Tetradentate-arm Schiff base derived from the condensation reaction of 3,3′-dihydroxybenzidine, glyoxal/diacetyl and 2-aminophenol: Designing, structural elucidation and properties of their binuclear metal(II) complexes

Synthesis and Characterization of Ni(II)/Zn(II) Metal Complexes Derived from Schiff Base and Ortho‐Phenylenediamine: In vitro DNA Binding, Molecular Modeling and RBC Hemolysis

“…In complexes 1 and 2 , the peak for the intraligand transition was slightly shifted at 280 nm in addition to the peak at 367 nm for 1 while in 2 shoulder obtained at 324 nm was assigned to the LMCT transitions of ligand coordinated to the metal. Besides this complex 1 displayed a low‐intensity band in the visible region at 500 nm and broad 668 nm assigned to 1 A 1 g→ 1 A 2 g and 1 A 1 g→ 1 B 1 g transition characteristic of square planar Ni(II) complexes . However, complex 2 does show any band in the visible region due to the absence of d–d transition.…”

Spectroscopic, Physical and Topography of Photochemical Process of PVC Films in the Presence of Schiff Base Metal Complexes

“…The Ni(II) complex ( T d ) shows absorption band at 591 nm which corresponds to 3 T 1 (F) → 3 T 1 (P) transition [ 32 ]. The Cu(II) Schiff base complex ( D 4h ) shows a band at 494 nm related to 2 B 1g → 2 A 1g transition [ 33 , 34 ]. It should be noted that the difference of coordination atoms is negligible.…”

Synthesis, Spectroscopic Characterization And Antimicrobial Evaluation of Novel Nitrogen Containing Metal Complexes

“…Schiff bases are azomethine group (C=N) containing compounds which were first announced by Hugo Schiff in 1864 and synthesized by condensation of the primary amine with carbonyl compound [1]. Schiff bases remain the most extensively utilized organic compounds [2][3][4][5][6][7] and it has potential sites, such as nitrogen and other electron donors; it may be related to their stability, uses and applications in numerous scientific areas [1,2,4,5,[8][9][10]. For long periods of time, coordination chemistry of Schiff base ligands has been the topic of great interest.…”
