Synthesis, spectroscopic characterization and biological evaluation studies of Schiff’s base derived from naphthofuran-2-carbohydrazide with 8-formyl-7-hydroxy-4-methyl coumarin and its metal complexes

Synthesis of novel macrocyclic Schiff's‐base and its complexes having N2O2 group of donor atoms. Characterization and anticancer screening are studied

“…[32][33][34][35] This is due to the coordination of azomethine nitrogen to metal ion. [36,37] Also, a broad ν(H 2 O) band of 5 is found at 3260 cm −1 .…”

DFT calculations, spectroscopy and antioxidant activity studies on (E)-2-nitro-4-[(phenylimino)methyl]phenol

“…Experimentally obtained geometric parameters and their corresponding values in the optimized structure are given in Table 2 [22,24] and the C7@N2 bond having double bound character is also evidence for the conjugation. Dihedral angle between the two rings (C1AC6 and C8AC12) is 41.19°a nd molecule is not planar.…”

“…These papers contain such subject as synthesis, coordination chemistry application, crystal structure determination, ab initio and DFT calculations, vibrational characteristics, antioxidant, antibacterial activities, the free radical scavenging activities and non-linear optic properties [19][20][21][22][23][24][25][26][27][28][29][30][31].…”

Synthesis, characterization, and biological activities of oxovanadium(IV) and cadmium(II) complexes with reduced Schiff bases derived from N,Nʹ-o-phenylenebis(salicylideneimine)

“…Antioxidant activity of Schiff bases and their complexes has attracted much attention and has been widely investigated (Taha et al, 2011;Halli et al, 2012;Ravichandran et al, 2014). Most experiments were carried out using the DPPH test.…”
