Preparation and structural studies on organotin(IV) complexes with flavonoids

Journal of Radioanalytical and Nuclear Chemistry, 1998
Fourteen complexes of di-n-butyltin(IV)2+ cations with flavonoid glycosides (rutin, hesperidin, 2′,4′,3-trihydroxy-5′,4-dimetoxychalkone 4-rutinoside) and flavonoid aglycones (quercetin, morin, hesperitin and sorte flavones) were prepared. The composition of the complexes was determined by standard analytical methods.

Synthesis, spectral characterization and bio-analysis of some organotin(IV) complexes

European Journal of Medicinal Chemistry, 2008
Five novel organotin(IV) derivatives have been synthesized by refluxing trimethyl, triethyl, tributyl, and triphenyl and tribenzyltin chloride with Schiff base derived from salicylaldehyde and adenine. These compounds were characterized by spectroscopic (IR, (1)H, (13)C, (119)Sn-NMR, (119m)Sn Mössbauer) techniques and elemental analysis. Based on these

Recent advancements in DNA interaction studies of organotin(IV) complexes

Inorganic Chemistry Communications, 2018
Abstract DNA interaction studies of organotin(IV) complexes have got tremendous attention during the recent years due to their anticancer and antitumor properties. Most of the chemotherapeutic organotins are DNA-targeted as they recognize specific DNA sequences, alter the local DNA structure, inhibit access to the activator or repressor protein and ...

Organotin(IV) complexes of thiohydrazides and thiodiamines: synthesis, spectral and thermal studies

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2006
Organotin(IV) complexes of tribenzyltin(IV) chloride and di(para-chlorobenzyl)tin(IV) dichloride with thiohydrazides have been reported. The ligands synthesized were bidentate coordinating through sulphur and terminal nitrogen atoms. These form 1:1 metal-ligand complexes. The following organotin(IV) complexes have been synthesized: (C(6)H(5)CH(2))(3)Sn(

Antimicrobial and mutagenic properties of organotin(IV) complexes with isatin and N-alkylisatin bisthiocarbonohydrazones

Journal of Inorganic Biochemistry, 2005
A new series of ligands is synthesised starting from thiocarbonohydrazide and isatin (H(2)itc) or N-alkylisatin (methyl, H(2)mtc; butyl, H(2)btc; pentyl, H(2)ptc); the X-ray structure of H(2)mtc is discussed. The bis imine ligands are reacted with diorganotin(IV) compounds, obtaining monometallic complexes.

Azine Derivatives of 5,5′-Dithiobis(salicylaldehyde) and Their Organoxytitanium(IV) and Organotin(IV) Complexes

Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1986
Abstract 5,5′-Dithiobis(salicylaldehyde) reacts with salicylaldehyde hydrazone or 2-hydroxyacetophenone hydrazone forming new dithiobis(diazine) derivatives containing four OH, two N-N and one S-S groups. The products have been characterized by elemental analyses, IR, PMR and mass spectral studies.
