Bis[2,3-bis(4-chlorophenyl)propenoato-κ²O:O′]di-n-butyltin(IV)

Abstract

The crystal structure of the title compound, [Sn(C4H9)2(C15H9Cl2O2)2], has a highly distorted octahedral geometry that may be best described as a skew‐trapezoid planar geometry with two additional axial ligands. The carboxyl­ate ligands are asymmetrically coordinated to the Sn atoms, with short Sn—O covalent bonds [mean 2.098 (6) Å] and long dative bonds [mean 2.602 (12) Å]. The mean Sn—C distance for the n‐butyl groups is 2.117 (13) Å, with a C—Sn—C angle of 139.18 (18)°.

Structural chemistry of organotin(IV) complexes

“…Representative structure of this class is given in Fig. 8 [34]. The structure is composed of discrete monomeric molecules in which six-coordinated Sn atoms are bonded to two n-butyl groups and two 2,3-bis(4-chlorophenyl)propenoates ligands.…”

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.…”
