Thermal degradation analysis of organotin(IV) esters

Journal of the Iranian Chemical Society, 2009
The di- and tri-organotin(IV) complexes of n-butyl hydrogenphthalate and (Z) 3-(4-nitrophenyl)-2-phenyl-2-propenoate were subjected to thermal decomposition by mean of thermogravimetry (TG). The decomposition occurred in steps and the kinetics of every set of reactions was determined using the method described by Coats and Redfern.

Biologically active organotin(IV) schiff base complexes

Journal of the Iranian Chemical Society, 2010
Organotin(IV) complexes with the general formulae R3ML [R: alkyl (Et, Ph and Bz), M: Sn and L: 1,3-bis(2hydroxybenzylidene)thiourea were synthesized. The newly synthesized schiff base and its complexes were characterized by elemental analysis, melting point, molecular weight determination, IR and NMR [ 1 H, 13 C and 119 Sn] spectral methods.

Performance Study of Organotin (IV) Complexes

International Journal of Organic and Inorganic Chemistry, 2018
Organotin(IV) complexes possess at least one covalent carbon to organotin bond as part of its structural characteristics [1]. It also contains tin in a +4 oxidation state bonded to donor atoms of a number of ligands. They have received a lot of research interests due to their structural diversity and numerous applications [2].

New tin(IV) and organotin(IV) chelates of ferrocenyl hydrazones

Inorganica Chimica Acta, 1983
Several new tin(IV) and organotin(IV) complexes of the composition R2SnL2 (where R = chloro, butyl or octyl group and L = ferrocenyl hydrazone anion) have been synthesized by reacting tin(II) dichloride hydrate, dibutyltin(IV) oxide and dioctyltin(IV) oxide with ferrocenyl hydrazones of the type (where Fc = ferrocenyl moiety and Ar = phenyl, p ...

Mössbauer spectroscopy of mono-organotin(IV) derivatives

Inorganica Chimica Acta, 1974
Abstract The Mossbauer parameters isomer shift, δ, and quadrupole splitting, ΔE, of mono-organotin compounds insofar investigated have been collected and tabulated. It is demonstrated that isomer shifts consistently depend on ligand electronegativities and coordination numbers, from which it is deduced that RSn IV behave much more as Sn IV rather ...

Bioactive versatile azomethine complexes of organotin(IV) and organosilicon(IV)

Applied Organometallic Chemistry, 1998
Diorganotin(IV) and diorganosilicon(IV) derivatives of the types R 2 MCl(TSCZ) and R 2 M(TSCZ) 2 (where TSCZ is the anion of a thiosemicarbazone ligand, R = Ph or Me and M = Sn or Si) have been synthesized and characterized by elemental analyses, molecular weight determinations and conductivity measurements. The mode of bonding has been established on

Tin(IV) Oxide Coatings from Hybrid Organotin/Polymer Nanoparticles

ACS Applied Materials & Interfaces, 2011
Tin dioxide coatings are widely applied in glasses and ceramics to improve not only optical, but also mechanical properties. In this work, we report a new method to prepare SnO(2) coatings from aqueous dispersions of polymer/organotin hybrid nanoparticles.
