Recent Advancements in Organotin(IV) Complexes as Potential Anticancer Agents

Anti-Cancer Agents in Medicinal Chemistry, 2018
Cancer is a multistep disease incorporating physical, chemical, environmental, metabolic and genetic factors, which play direct or indirect role in the induction and deterioration of cancer. Many of the platinum based drugs were synthesized but due to their systemic toxicity, broad spectrum of action, intrinsic and acquired drug resistivity, it has ...

Chemistry and applications of organotin(iv) complexes of Schiff bases

Dalton Transactions, 2011
Schiff bases are the most widely used versatile ligands, able to coordinate many elements and to stabilize them in various oxidation states. Recently, this class of compounds has been employed as models for biological systems, and in control of stereochemistry in six-coordinate transition metal complexes.

Synthesis and Structure of Organotin(IV) Complexes of Maltol

Chemische Berichte, 1994
A series of organotin(IV) maltol complexes R4 — xSnLx (1–4, 6; x = 1–3) and the dichloro‐compound Cl2SnL2 (5) have been prepared and characterized on the basis of their IR‐, 1H‐, 13C‐ and 119Sn‐NMR data. While an X‐ray crystal structure analysis of Ph2SnL2 (4) and Cl2SnL2 (5) reveals distorted cis‐octahedral structures, the Me2SnL2 molecule (2) adopts ...

Equilibrium studies of organotin(IV) complexes with vitamin B6

Talanta, 1997
The complex-formation equilibria of dimethyltin(IV), trimethyltin(IV) and tributyltin(IV) with pyridoxamine were investigated in dioxane-water mixtures and at different temperatures using a potentiometric technique. The stepwise formation constants of the complexes formed in solution were calculated using the non-linear least-square program MINIQUAD-75.

Organotin(IV) complexes with imidazo[1,2-a]pyridines

Polyhedron, 2014
Abstract The three-components reaction of dimethyltin dibromide with imidazo[1,2-a]pyridine and allyl bromide in ethanol affords an ionic complex, bis(1-allylimidazo[1,2-a]pyridinium) dimethyltetrabromostannate(II). X-ray crystal structure analysis of the complex reveals the tin atom to be hexacoordinated, forming a dianion.

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].
