Synthesis, characterization, thermal, and antimicrobial studies of binuclear metal complexes of sulfa-guanidine Schiff bases

Preparation, spectral characterization and antimicrobial activity of binary and ternary Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Ce(III) and UO2(VI) complexes of a thiocarbohydrazone ligand

“…The electronic spectra of the Zinc(II) complexes (13 and 14) exhibited bands in the range 470-510 nm which may be attributed to charge transfer transitions [57]. Based on elemental analyses and IR spectral data, octahedral structures were suggested for these complexes.…”

Synthesis, spectral characterization, and antimicrobial studies of metal complexes of the Schiff base derived from [4-amino-N-guanylbenzene sulfonamide] and salicylaldehyde

“…Schiff-base metal complexes involving sulfaguanidine and salicylaldehyde are expected to possess enhanced biological activities [1][2][3][4][5][6][7][8][9][10][11]. In this connection, sulfaguanidine condensed with salicylaldehyde offers an extension to the study since perturbation in the ligand backbone may affect the stereochemistry of the complexes.…”

“…Metal complexes of Schiff bases derived from sulfaguanidine have been investigated [10]. Schiff-base metal complexes involving sulfaguanidine and salicylaldehyde are expected to possess enhanced biological activities [1][2][3][4][5][6][7][8][9][10][11].…”

Synthesis, Structural Characterization, and Antimicrobial Activities of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) Complexes of Triazole-based Azodyes

“…51 The negative contribution of the g eff values of the investigated complexes to the value of the free electron, 2.0023, indicates an increase in the covalent nature of the bonding between the metal ion and the ligand molecule. 52 No hyperfine structure was observed (Figure 2). …”
