Synthesis, characterisation and X-ray structures of diorganotin(IV) and iron(III) complexes of dianionic terdentate Schiff base ligands

Synthesis, characterization, and in vitro antimicrobial activities of organotin(IV) complexes of Schiff bases with ONO‐type donor atoms

“…Remarkably, in the mass spectra of Me 2 SnL 3 , n-Bu 2 SnL 3 , and Me 2 SnL 4 , the base peaks correspond to the whole ligands. The fragmentation patterns are also in agreement with the literature reports [8,42,43].…”

Iron(III) and copper(II) complexes bearing 8-quinolinol with amino-acids mixed ligands: Synthesis, characterization and antibacterial investigation

“…Efforts to grow single crystals of complexes suitable for X-ray crystallography using variety of different techniques and solvent combinations have been unsuccessful. However, the elemental analysis results fit well with the proposed molecular formula; and on the basis of FT-IR and electronic transitions spectra we were able to predict the metal coordination upon the shift to lower energy level or disappearance in the vibrational frequencies of the donor atoms synonymous with previous reports(Labisbal et al, 2006;Anacona, 2004).For iron complexes 4a-b, there is disappearance of hydroxyl (O-H) hydrogen bond attributed to coordination with the iron metal centre. The carbonyl group (C=O) vibrational frequency appeared red shifted with very weak intensity.…”

Synthesis, characterization, spectroscopic and crystallographic investigation of Cobalt(III) schiff base complex with two perpendicular diamine coumarin ligands

“…In the past decade, Schiff bases have received much attention, mainly because of their extensive applications in the synthesis of coordination compounds and catalysis [13][14][15][16][17]. This is due to the fact that Schiff bases offer opportunities for inducing substrate chirality, tuning factors of metal centered electronic and improve the solubility and stability of homogeneous or heterogeneous catalysts, i.e.…”
