Heterobimetallic complexes containing iron (II) and hexa-coordinated organosilicon

Abstract

Heterobimetallic complexes of the type R 2 Si(HL)Cl 2 and R 2 SiL 2 (where R = Me, Et, Ph; L = ferrocenyl aroylhydrazone) have been synthesized at 40• C to 50• C and at room temperature (25

Bioactive Penta-Coordinated Diorganotin(Iv) Complexes of Pyridoxalimine Schiff Bases

“…15 In the spectra, some new bands assigned in the region 517-577 cm −1 , 616-742 cm −1 , and 446-529 cm −1 were due to Sn-O, Sn-C, and Sn-N bonds that were absent in the precursors, further indicated formation of complexes. 12 …”

“…10 We are more concerned with the antimicrobial activity of organotin(IV) compounds, keeping this in mind and in continuation of our work, on the synthesis of biologically active compounds containing N, O, S, and their organotin/silicon complexes. [11][12][13][14] We report the synthesis of new complexes of Schiff bases derived from the condensation of pyridoxal hydrochloride with derivatives of aminophenol and studied the effect of introducing tin on the activity of the ligand.…”

Evaluation of bactericidal and fungicidal activity of ferrocenyl or phenyl derivatives in the diphenyl butene series

“…Ferrocenyl derivatives of thiazoloacylhydrazone [30] and of various peptides [31] have been found to be active on Staphylococcus aureus, Esherichia coli and Pseudomonas aeruginosa. Ferrocenyl aroylhydrazones have shown moderate activity on bacteria and fungi [32,33]. A ferrocenyl analog of the antifungal fluconaxole has also been synthesized and its activity is modest compared to that of the corresponding organic compound [34].…”

Synthesis, Spectral, andIn VitroAntibacterial Studies of Organosilicon(IV) Complexes with Schiff Bases Derived from Amino Acids

“…A characteristic band at 3250 cm −1 , due to ν (N–H) of indole, was observed in the spectra of the ligand and their silicon complexes. Several new bands of strong to medium intensity in the spectra of the complexes at 1272 ± 5 and 760 ± 5 cm −1 may be due to the asymmetric deformation mode of Si–CH 3 and stretching vibrations of Si–C, respectively [36, 37]. …”
