Copper (II) complexes of a hydrazone ligand bearing quinoline moiety: Preparation, spectral, antitumor, and molecular docking studies

“…(vii) The sulfato complex exhibited two strong bands around 1,227 and 1,163 cm −1 , which may be attributed to the coordinated sulfato group in a bidentate fashion 28,29,33 . (vii) The mixed‐ligand complexes bearing the phen (5) or oxine (6) moieties displayed new bands (1,508–1,500 cm −1 ), which are related to ν(C=N) of the heterocyclic rings lending further support of the participation of the secondary ligand in coordination 37–41 …”

“…28,29,33 (vii) The mixed-ligand complexes bearing the phen (5) or oxine (6) moieties displayed new bands (1,508-1,500 cm À1 ), which are related to ν(C=N) of the heterocyclic rings lending further support of the participation of the secondary ligand in coordination. [37][38][39][40][41]…”

Structural versatility in nickel (II) complexes of a hydrazone ligand based on alloxan: Preparation, spectroscopic, DFT, anticancer, and molecular docking studies

“…All these results are consistent with the neutral characters of the complexes obtained from molar conductivity measurements. (d) The mixed phen ( C5 ) or oxine ( C6 ) complexes showed additional bands at 1552 and 1497 cm −1 , correspondingly, which might be ascribed to the secondary ligand's v(C=N) 52,53 …”

Synthesis, Spectroscopic Characterization and Thermal Studies of Polymer-Metal Complexes Derived from Modified Poly Styrene-Alt-(Maleic Anhydride) as a Prospects for Biomedical Applications

“…PSMAM-Cu(II) complex displays absorption bands at 211, 253, 293, 353 and 394 nm. The first regional bands at 211-272 nm correspond to a π →π* transitions, whereas the bands existed at 362-415 nm region can be assigned to n→π* transitions type [53][54][55][56]. The solid reflectance spectra of the complexes (1) and (2) demonstrate four weak intensity absorption bands in the ranges of (16.666-16.233), (31.347-27.397), and (38.461-36.764) cm −1 (Table 3).…”
