Organotin(IV) Carboxylates of Substitutedα‐Cinnamic Acid, RnSn(OCOC(R2)=CHR1)4 –n: Synthesis, Spectroscopic Characterization and Biological Evaluation

“…A broad and strong band associated with the hydroxyl (OH) group of the phenolic ring of ligand moiety is observed in the range 3380–3122 cm −1 , which rules out any coordination to the Sn atom via phenolic OH . The data obtained are consistent with the formation of well‐defined diorganotin(IV) 1 , 3 , 4 and triorganotin(IV) 2 , 5 , 6 complexes, which is confirmed by the presence of υ(Sn–O) and υ(Sn–C) bands in the range of 475–459 and 580–553 cm −1 , respectively, and shifting of υ(COO) bands to lower frequencies for all the complexes . The difference of Δυ between υ(COO) asym and υ(COO) sym vibrations gives important information about the molecular arrangement in such complexes.…”

Synthesis, structural elucidation, and biological activity to organotin(IV) derivatives of (E)‐2,3‐bis(4‐chlorophenyl)‐2‐propenoic acid

“…Keeping theses aspects under consideration, in continuation to our previous work, we report here the synthesis and characterization of organotin(IV) derivatives of ( E )‐2,3‐bis(4‐chlorophenyl)‐2‐propenoic acid and their antibacterial, antifungal, and cytotoxicity studies. Cinnamic acid is a naturally occurring unsaturated carboxylic acid that has low toxicity and a broad spectrum of biological activities.…”

“…The IR data play an important role in characterizing organotin(IV) carboxylates. There are two important ways of characterizing organotin(IV) carboxylates: firstly by comparison with that of precursors and then with that of the reported data, and secondly, verification of functional group presence . The coordination of carboxylate group is decided on the basis of the Δν[ν(OCO) asym‐ ν(OCO) sym ] in organotin compounds .…”

“…The characteristic resonance peaks in the 1 H NMR spectra of compounds 1‐8, and free ligand is given in experimental part. The spectra were assigned on the basis of peak intensity, multiplicities, and comparison with the literature values reported earlier …”

“…The biochemical activity of organotin(IV) compounds is based on the structure and coordination number around the tin moiety. [10][11][12] Keeping theses aspects under consideration, in continuation to our previous work [15][16][17][18][19][20][21][22][23][24][25][26] , we report here the synthesis and characterization of organotin(IV) derivatives of (E)-2,3-bis(4-chlorophenyl)-2-propenoic acid and their antibacterial, antifungal, and cytotoxicity studies. Cinnamic acid is a naturally occurring unsaturated carboxylic acid that has low toxicity and a broad spectrum of biological activities.…”
